Ir stretch at 3000
WebSep 24, 2015 · 4. "C-H" Stretching The aromatic "C-H" stretch is usually weak and occurs at "3100-3000 cm"^-1. The aliphatic "CH"_3 group shows stronger symmetric and antisymmetric stretches at "2960 cm"^(-1) and "2870 cm"^(-1). Here's the actual IR spectrum of methyl benzoate. (from chemistrytextbookcrawl.blogspot.com) WebApr 1, 2002 · The IR-spectrum can be divided into five ranges major ranges of interest for an organic chemist: a. From 2700-4000 cm-1(E-H-stretching: E=B, C, N, O) In this range typically E-H-stretching modes are observed. The C-H-stretching modes can be found between 2850 and 3300 cm-1,depending on the hydrization.
