Advances in Luminescence Spectroscopy: A Symposium
The recent thrust of their work has been with biacetyl as the acceptor molecule, a
species that is certainly an anomoly in photophysics. It is the only aliphatic
molecule known to phosphoresce in fluid solution and has been termed "
pathologic" ...

We have studied (4-40) x 10~5m biacetyl in benzene solution using a sodium
nitrite filter to isolate the visible range, and found a spectrum similar to that given
by these authors; however, a permanent consumption of 1-2% biacetyl per flash ...

Decomposition and Isomerization of Organic Compounds
The difference in the effect, caused by biacetyl, at the two wavelengths was
interpreted by the assumption that the higher vibrational levels of the excited
singlet state, involved at the shorter wavelengths, are less effective in respect of
energy ...

Laser Diagnostics for Combustion Temperature and Species
It was chosen because of its very close match to the vaporization rate of iso-
octane making it superior to biacetyl for this purpose. Biacetyl (CH3-(CO)2-CH3)
has been widely utilized as a seed (Lozano et al., 1992) due to its very low
toxicity.

absorption directly in an excited singlet state. Subsequently biacetyl falls down to
its triplet state T1. In absence of a quencher, the following step is the return to the
