- 中文摘要: Decays of fluorescence of h4¯ and d4¯acetaldehyde are measured. The quantum-beat structure is observed for both isotopic species. This oscillatory phenomenon is due to interaction of the state S1(A1 A”) and T1. Below the dissociation threshold to from products methyl and formyl radicals, an upper limit of a lifetimc is set at 195-800 ns for perturbed triplet states of CD3CDO; the lifetime is calculated directly from the linewidth of Fourier-transformed spectra. At excitation wavelength shorter than 316.12 nm, the transformed linewidth increases, indicating the onset CD3 + DCO formation.
