## Abstract FTIR and FT Raman spectra of 2βbromoβ4βchloro phenol (BCP) and 2βchloroβ4βnitro phenol (CNP) were recorded in the region 4000β400 and 4000β50 cm^β1^, respectively. The molecular structure, geometry optimization, and vibrational wavenumbers were investigated. The spectra were interpreted
