Analysis of IR Spectra of bromobenzene
3100cm-1 - C-H(aromatic) stretching vibrations
* Weak combinations and overtones bands are appears in the range of 2050 - 1650cm-1 .
1600-1500cm-1 - C=C stretching of aromatic ring
1070-1000cm-1 - =C-H bending absorption
750-650cm-1 - C-Br stretching absorption bands
please rate my answer thankyou.
