The IR and Raman spectra of ethyl salicylate were recorded and analyzed. The surface enhanced Raman scattering (SERS) spectrum was recorded in a silver colloid. The vibrational wavenumbers of the compound have been computed using the Hartree-Fock/6-31G* basis. The direction of charge transfer ...

At times, with extremely weak spectrum, we've tried going to the extreme of running 1000 or even 10000 spectrum. Besides taking a very long time, it didn't really help much. There was enough drift in the baseline signal to mess up the spectrum. ...

Raman is able to determine from a spectrum on the arm the nature of the sunscreen being used. A: ODPABA (octyl N,N-dimethyl-p-aminobenzoic acid) ,二甲基对氨基苯甲酸辛酯 B: OMC (octyl p-methoxycinnamate) ,甲氧基肉桂酸辛酯 C: BZ3 (oxybenzone) ,羟基苯酮 D: OCS (octyl salicylate) ,...
The presence of CH3, \\{CH2\\} and \\{CO2\\} modes in the \\{SERS\\} spectrum indicates the nearness of the methyl group to the metal surface which affects the orientation and metal molecule interaction. The presence of phenyl ring modes in the \\{SERS\\} spectrum indicates a ...
