Photodissociation of uracil

Physical Chemistry Chemical Physics, 2007
We investigate the photochemistry and photodissociation dynamics of uracil by two-colour photofragment Doppler spectroscopy and by two-colour slice imaging at excitation wavelengths between 268 and 235 nm. We observe the loss of a hydrogen atom upon excitation into the pipi* state.

Photodissociation of thymine

Physical Chemistry Chemical Physics, 2006
We discuss the photochemistry and photodissociation dynamics of thymine as revealed by two-colour photofragment Doppler spectroscopy and by one-colour slice imaging. Thymine is optically excited into the pipi* state, known to deactivate quickly.

Photodissociation dynamics of pyridine

The Journal of Chemical Physics, 2005
Photodissociation of pyridine, 2,6-d2-pyridine, and d5-pyridine at 193 and 248nm was investigated separately using multimass ion imaging techniques. Six dissociation channels were observed at 193nm, including C5NH5→C5NH4+H (10%) and five ring opening dissociation channels, C5NH5→C4H4+HCN, C5NH5→C3H3+C2NH2, C5NH5→C2H4+C3NH, C5NH5→C4NH2+CH3 (14%), and ...

Molecular photodissociation

The Journal of Chemical Physics, 1974
In this paper we present a quantum mechanical model for direct photodissociation and for predissociation of polyatomic molecules in terms of a sequential decay scheme involving multiple coupled continua, where each continuum corresponds to a different internal vibrational state of the fragments.

Photodissociation of ultracold diatomic strontium molecules with quantum state control

Nature, 2015
Chemical reactions at ultracold temperatures are expected to be dominated by quantum mechanical effects. Although progress towards ultracold chemistry has been made through atomic photoassociation, Feshbach resonances and bimolecular collisions, these ...
