Page 124: equation (4.34), subscript on W after the summation should be: 2n+1-k-l not 2n+1-k-1 (i.e. the last character should be an L and not a 1 (one)).

Page 125: equation (4.35), first equation: psii should be psi1.

Page 141: equation (4.67), last equation, the operator r13 should be r34.

Page 184, equation (6.22): In the denominator, the term beta4x3 should be beta4x4.

Page 186, equation (6.28), third line: In the definition of delta, the exponent of the first rho should be -1/3, and not +1/3, i.e. delta = crho-1/3.

Page 207, equation (8.11), first line: The matrix alpha in the parenthesis should be sigma, analogous to that in the second line.

Page 224-225: P. Popelier has pointed out that the discussion of AIM charges in section 9.3, and especially Figure 9.3, may be misleading.
For a given atomic basin, the electron density as seen from the outside gives rise to an electrostatic potential, which may be expanded in terms of electrical moments. The electron density may be integrated and combined with the nuclear charge to give a net charge, the first moment, which is the AIM "atomic charge". Higher order atomic moments (dipole, quadrupole etc.) may similarly be defined by suitable integrations of the electron density.
If the net charges are taken as nuclear centered (analogous to partial charges for force field methods) they do not reproduce the molecular dipole, quadrupole etc. moments, nor do they yield a good representation of the electrostatic potential. They are therefore not suitable for transferring to a force field environment for modelling purposes.
If, however, the dipole moments of the atomic basins are also considered, the total molecular dipole moment is reproduced, and similarly for higher order moments. The dipole moment of CO, for example, is close to zero (0.122 D), despite calculated AIM charges of +/- 1.1. The large charge transfer is almost exactly canceled by compensating atomic dipoles.
C. L. Perrin (ref. 14) has attributed the large AIM charges to orbital effects, as illustrated in Figure 9.3. C. Gatti and P. Fantucci (J. Phys. Chem. 97 (1993) 11677), however, have shown that Perrins arguments are only valid if orbital overlaps are neglected. For ab initio wave functions this is not a valid approximation.

Page 228, equation (9.25), a summation over i (occupied MOs) is missing (or implicitly included by the summation over the atoms A ... ).

Page 243, equation (10.33), middle equation: The derivative of the CI wave function on the right hand side is not with respect to C but with respect to c (i.e. not all parameters, just the MO-coefficients), i.e. dpsiCI/dC --> dpsiCI/dc.

Page 245, equation (10.42), second equation: There are a couple of sign errors: (F(0) - S(0)eps(0))C(1) = (-F(1) + S(0)eps(1) + S(1)eps(0))C(0)

Page 290-294, Tables 11.25-11.33: in calculating the MAD as a measure of the performance of different methods for calculating relative energies, the lowest energy isomer has (arbitrarily) been selected as the zero point. Unfortunately, the MAD calculated in this fashion depends on which isomer is selected as the reference structure. A better definition is to calculate the MAD relative to a reference energy defined as the average of all the structures. This will lead to changes in the exact MAD values, although the conclusions regarding the performance of different methods are unaffected.

Page 303, equation (12.22), the formula for Strans: The factor 5/2R is correct! (this page has previously reported that it should be changed to 3/2R).

Page 303, equation (12.22), the formula for Srot: The factor 1/2 should only go with the 3 on the inside of the parenthesis, i.e. Srot = R[3/2 + ln(...)].

Page 307, equation (12.27), the formula for deltaS= is missing a term delta(n)ln(RT) inside the square bracket, i.e. deltaS= = R[ln(A) - ln(kT/h) - (1-delta(n)) + delta(n)ln(RT)].

Page 312, equations (13.13) and (13.14), and text between: The FG matrix is not the product of the F and G matrices, but should be taken as a matrix containing the product of the matrix elements, i.e. (FG)ij = FijGij.

Page 313, just below equations (13.18): The ra,b,c vectors are not the eigenvectors of the inertia matrix (which are of length 3), but vectors constructed from the eigenvalues of the inertia matrix and the atomic coordinates (i.e. vectors of length 3N). See ref 13.1 for details.

Page 323, line 11: The 3N-1, 3N-2 and 3N-3 should be N-1, N-2 and N-3, i.e. For a simple acyclic system these may be chosen as N-1 distances, N-2 angles and N-3 torsional angles, ...

Page 374, equation (16.6): There is a factor of 1/Nstates missing in the numerator of the second and third equations, since the "1" is being replaced by 1/Nstates times a sum over eEi/kTe-Ei/kT. This constant factor can be separated out and just corresponds to a shift in the zero point for the Helmholtz free energy.

page 9, just after eq. (2.5), the k is the force constant when the Taylor factor of 1/2 is written explicitly, in contrast to the (second order) force constants k2AB in eqs. (2.3), (2.4) and (2.6) where the factor is included in the constant. This is formally correct, as k in eq. (2.5) is not stated to be the same as k2AB but this should have been made clear. The sqrt just after eq. (2.5) could be written as sqrt(k2AB/D) to be consistent.

Page 29, line 13: word missing: ... for comparing with experimental data.

Page 30, parameter estimates: the correct number of independent stretch parameters for N atom types is N(N+1)/2, not N*N/2, thus the 900 parameters should be 930 instead. Similar changes hold for the estimated number of bend and torsional parameters.

Page 160, line 6 from the bottom: the TZ type DH basis is a (12s9p) primitive basis set contracted to [6s5p] (not (13s9p) --> [6s4p]) with the contractions 6,3,1,1,1,1 for the s-functions (note doubling of one function) and 4,2,1,1,1 for the p-functions.
