β¦ Synopsis
The emission spectrum of lyoluminescence of acridine orange was recorded on a Fuess spectrograph. A continuous emission band was observed from 500 to 640 nm. On resolution, it showed two-banded emission with peaks at 565 and 603 nm respectively. The colour centers released during dissolution of irradiated NaCl crystals in aqueous acridine orange solution react to produce excited dimer and trimer species of acridine orange. It is suggested that these excited species are responsible for the observed lyoluminescence emission spectrum of acridine orange.

## Abstract The absorption spectra and circular dichroism (CD) have been measured for aqueous solutions of acridine orange of a constant concentration, [__D__] = 5 Γ 10^β5^__M__, mixed with poly(__S__βcarboxyethylβLβcysteine) in various mixing ratios, [__P__]/[__D__], ranging from 330 to 11, at dif
The effects of ?-irradiation on the browning reaction in the model system of fructose-phenylalanine solution were investigated. The optical absorption recorded for irradiated and heated solutions of fructose-phenylalanine was different from those of only irradiated or only heated solutions. T o exp
