Photodissociation of acetaldehyde, CH$$_{3}$$CHO$$rightarrow$$CH$$_{3}$$+HCO; Direct ab initio molecular dynamics study

Kurosaki, Yuzuru; Yokoyama, Keiichi

Chemical Physics Letters, 371(5-6), p.568 - 575, 2003/04

A total of 400 trajectories for the photodissociation, CH$$_{3}$$CHO$$rightarrow$$CH$$_{3}$$+HCO, on the T$$_{1}$$ potential surface have been calculated using the direct ab initio molecular dynamics method at the UB3LYP/cc-pVDZ level of theory. It was predicted that the product CH$$_{3}$$ is neither vibrationally nor rotationally excited and HCO is vibrationally not excited but rotationally excited. The averaged HCO rotational energy was calculated to be 1.1 kcal/mol, which is 15.1 % of the available energy, 7.3 kcal/mol. The present result agrees with experiment within just a few percent of the observed data.

Photodissociation of acetaldehyde, CH$$_{3}$$CHO$$rightarrow$$CH$$_{4}$$+CO: Direct ab initio dynamics study

Kurosaki, Yuzuru; Yokoyama, Keiichi

Journal of Physical Chemistry A, 106(47), p.11415 - 11421, 2002/11

 Times Cited Count:37 Percentile:72.57(Chemistry, Physical)

A total of 100 trajectories for the photodissociation, CH$$_{3}$$CHO $$rightarrow$$ CH$$_{4}$$ + CO, on the S0 potential surface have been calculated using the direct ab initio molecular dynamics method at the RMP2(full)/cc-pVDZ level of theory. The energy distributions for the relative translational energy, the CO internal energy, and the CH$$_{4}$$ internal energy were calculated to be 28, 20, and 51 %, respectively. It was predicted that the product CO is highly rotationally excited but vibrationally almost not excited; on average, the rotational and vibrational quantum numbers were 68.2 and 0.15, respectively, which qualitatively agrees with the recent observation of Gherman et al. (J. Chem. Phys. 2001, 114, 6128.)
