To review then, the useful group wavenumbers for benzene rings are one or more C-H stretches between 3100 and 3000 cm -1, one or more sharp ring modes between 1620 and 1400 cm -1, and an intense ring bend from 1000 to 700 cm -1. Most of the time when a benzene ring is encountered it contains one or more substituents.

FTIR & UV-Vis analysis of Polymer(Polystyrene, LDPE) samples
WebbMass spectrometry is an analytical tool useful for measuring the mass-to-charge ratio (m/z) of one or more molecules present in a sample. These measurements can often be used to calculate the exact molecular weight of the sample components as well. Typically, mass spectrometers can be used to identify unknown compounds via molecular weight … WebbInfrared (IR) spectroscopy is a technique used to identify compounds based on … Webb5 mars 2013 · Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments.
