New views of collisional vibrational relaxation: Energy removal rates and energy distributions of triplet state pyrazine
Collisional energy removal rates from vibrationally excited T$\sb1$ pyrazine are measured using the refined and validated Competitive Radiationless Decay (CRD) method. Optical excitation followed by intersystem crossing ...
Energy dependence of collisional energy removal from vibrationally excited T(1) pyrazine
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 ...
Fullerene triplet states in solution
Triplet state pre-equilibration by reversible energy transfer has been observed by transient-absorption spectroscopy in mixed toluene solutions of C70 and C60 and of C70 and C60(CH 3)2. The equilibrium constants governing ...
An integrated interpretation of azomethane photodissociation dynamics
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, ...
