Notes:
The internal and translational energy distributions of nitric oxide, which was desorbed from a cold polycrystalline platinum foil by laser-induced thermal desorption, were measured using a laser-excited fluorescence, time-of-flight technique. Under irradiation conditions which are estimated to produce a maximum surface temperature of 320 K, desorbed NO in quantum states with 25〈ER〈2162 cm−1 were represented by two distributions of molecules: a translationally energetic component with a mean kinetic energy 〈ET〉/2k which continuously increased from 1400 to 2650 K with increasing ER, a rotational temperature of TR=410 K, and a vibrational temperature of TV(approximate)900 K; and a slower component with 〈ET〉/2k=300 K and TR=170 K.
