 Title: THE 274.8 NM BAND SYSTEM OF ANISOLE Creators: Balfour, W. J.; Ram, R. S. Issue Date: 1982 Abstract: The $\eta^{\ast} \leftarrow \eta$ electronic transition near 275 nm of anisole (methoxybenzene) and three deuterated isotopes has been photographed and a vibrational analysis performed. The spectrum shows a strong similarity that of $phenol^{1}$. The electronic origin bands of $C_{6}H_{5}OCH_{3}, C_{6}H_{5}OCD_{3}, C_{6}D_{5}OCH_{3}$ and $C_{6}D_{5}OD_{3}$ lie at 36 386.4, 36 389.6, 36 557.2, and $36 560.4 cm^{-1}$, respectively, Progressions and combination bands involving the totally symmetric vibrations 1, 6a, 7a, 9a, 12 and 18a account for most of the intensity in the spectrum. Many strong bands in the spectrum have associated with them sequence bands of out-of-plane vibrations, notably 16a, 16b and torsion about the $C_{6}H_{5}=O$ axis. The principal vibrational assignments will be reported and discussed. URI: http://hdl.handle.net/1811/29047 Other Identifiers: 1982-FC'-5
