Spectroscopy and nonradiative relaxtion of propynal Academic Article uri icon

abstract

  • The spectroscopy and relaxation dynamics of propynal in condensed media were studied by wavelength and time resolved laser-induced fluorescence techniques. Ã 1A′ fluorescence quantum yields are low, with intersystem crossing into the ã 3A′ state being the dominant relaxation pathway. The ã 3A′ state phosphorescence seems to occur in solid neon with near unity quantum yield. The very detailed spectroscopic information obtained from the emission and excitation spectra suggests a remarkably weak medium perturbation in solid neon. © 1982 American Institute of Physics.
