Solid state studies. Part VII. A single-crystal Raman study of the vibration of the Cr(CO)3 unit in hexa- and penta-methylbenzenetricarbonylchromium
Abstract
Single-crystal Raman studies of the isomorphous title compounds have shown that, whilst a vibrational factor-group method offers the simplest explanation of the 2000 cm–1 region, some features remain unexplained by it.
