Ir peak of c s
WebBasically IR peaks are the result of dipole radiation interactions for a compound, and stronger IR peak indicates stronger coupling between the light source and the dipole … WebSi—N=C=O 2280 Trimethylsilylisocyanate has a very strong —N=C=O band at 2280 cm-1. This band position is close to the high frequency end of the range 2275-2250 cm-1 for N=C=O attached to carbon. Si—CH 2 CH 2 CF 3 1210, 1130, 1070, 1025, 900 The 1210 cm-1 band is the strongest one of the set. Si—CH 2 Cl 1395, 1180
