Abstract
The infrared and Raman spectra of crystalline tetra-n-propylammonium bromide, (n-C3H7)4NBr, have been measured in the 3000 - 700Â cmâ1 region and vibrational assignments are proposed in part on the basis of the known crystal structure. Pressure-tuning infrared and Raman studies of this material were also undertaken using a diamond-anvil cell. There is a pressure-induced phase transition occurring between 1.8 and 2.1Â GPa, which is most likely a second-order transition. Some differences are noted between the infrared data reported here and those given in an earlier high-pressure infrared study. The spectroscopic results will be useful in examining zeolites involving (n-C3H7)4NBr as a template.
