Ethylenic band
Webethylenic band diminished by 43.7% and the new absorption bands exhibited maxima at 218, 241, 282 and 327 nm in the first minutes. The appearance of ethylenic band at 218 nm indicated the partially split of the two aromatic rings and it can be assigned to sodium salt of (2-Aminophenyl)acetic acid. The prominent absorption WebApr 14, 2016 · A similar effect may also be occurring for the high-frequency ethylenic component of GtACR1 with A1 retinal at 1545 cm −1, thus explaining the apparent upshift of the overall ethylenic band to 1537 cm −1. In this case, the higher-frequency component downshifts, causing an apparent upshift of the entire ethylenic peak.
