摘要：

Photodecomposition quantum yields for radical formation process from 11 single vibronic level in the Ã1A2 state of H2CO have been measured by monitoring the red HNO* chemiluminescence from the H + NO + M recombination. The quantum yield of H atom increases smoothly from ∼0.4 to 0.8 over ∼3000 cm-1 of excess vibrational energy. Experimental details of the laser induced HNO* chemiluminescence excitation spectroscopy are given. © 1979 American Chemical Society.
