dc.description.abstract The high resolution infrared spectrum of {gauche}-1,1,2-trifluoroethan(TFE) in a molecular beam in the region $3003-3007 cm^{-1}$ was obtained using optothermal detection. The sensitivity was increased using quadrupole focusing. When the quadrupoles had no potential difference, no spectrum was detected. The analysis of the band will be discussed, and the results will be compared with a homologous series of substituted ethanes. Previously, 2-fluoroethanol, {gauche}-1,2-difluoroethane, and {gauche}-and {trans}-1-chloro2-fluoroethane were studied. The earlier studies show that a correlation exists between than strength of intramolecular interaction and the extent of vibrational mode coupling. 2-Fluoroethanol, with the strongest interaction, has the most coupling. {Trans}-chloro-fluoroethane, with the least interaction, shows no peak fractionation. TFE will provide a test for this model, which predicts that the extent of coupling in TFE will be between that of 2-fluoroethanol and {gauche}-1,2-difluoroethane. en_US
