Before analyzing the comparison with experiments 8 it is necessary to note that experimentally the water populations are assigned to the (v1,3,v2) states due to experimental difficulties associated with the collisional coupling of populations in ν1 and ν3 stretching levels. Therefore, the QCT-AMN/PES-204 vibrational populations must be combined in the same way. So, v1,3 = v1+v3, refers to combined stretch modes, while v2 refers to the bend mode. Table lists the H2O population distributions obtained in the present theoretical study for the R2 path, together with the experimental evidence for comparison. The theoretical results reproduce the P1,3(n) and P2(n) distributions experimentally found, where the water product vibrational distribution is inverted in the stretching modes and not inverted in the bending mode. Although the agreement is not even quantitative, the present results are encouraging because these vibrational distributions are very difficult to determine experimentally, as proven by the fact that the same group reviewed this reaction and found opposite results. Thus, while in 2003 they reported that the P1,3(n) is not inverted and the P2(n) distribution is slightly inverted, in the 2021 revision 8 they reported the opposite behaviour.
