Frozen assay reagents have been used to reduce the rate of light emission from the rapid chemiluminescent acridinium ester and the bioluminescent firefly luciferase reactions. Melting of the assay reagent delays the initiation of the light emission, thus eliminating the need to initiate these rapid

β¦ Synopsis
The observation of light emission from bdnubm m an orgamc solvent as a result of the peroxyoxalate chemdummescence reaction IS reported for the first time The results presented herem indicate that blhrubm chemdummescence can be detected m N,N' dlmethylformamlde but not m chloroform, dlmethylsulfoxlde, or pyndme To eluadate this phenomenon, the effects of solvent on the chemdummescence intensity were examined as a function of solvent composition Furthermore, analytical utlhzatlon of the present observation for the determmatlon of bduubm m biological materials was evaluated Relative and absolute hmlts of detection were found to be 8 5 nmol I-' and 5 0 ng, respectively, and the response was found to be linear at least over three orders of magnitude Selectlvlty for the detection of blbrubm m the presence of a number of common interference species was also examined Finally, the vlslble spectrum of bovme serum m the blue-green region was obtained using the present chemdummescence method and was briefly compared with those obtained from absorption ad fluorescence methods

The CS + (A2Hi-X 2~+ ) emission has been observed in the C + (2p)+ocs reaction at thermal energy in a flowing afterglow apparatus. New bands of CS + (A 2 II~-X 2~ + ) from v'= 10-14 to v"= 0-3 were identified. The vibratio.nal populations in the CS + (A21-I~) state were estimated by spectral simulat
