In the first application of a new method for determining this information, rates of collisional vibrational energy removal have been measured for the T$\sb1$ state of pyrazine with vibrational energy contents ranging from ...

Although it has been known for more than 60 years that azoalkanes (R-N=N-R) dissociate under the influence of light or heat, few definitive conclusions have been reached on the mechanism of their photodissociation. Recently, ...
