INFRARED BAND STRENGTHS AND ABSORPTION CROSS-SECTIONS OF HFC-32 VAPOUR

摘要

Infrared absorbance cross-sections and integrated band strengths for HFC-32 (difluoromethane, CH2F2) vapour have been determined from laboratory measurements at eight temperatures (203, 212, 222, 243, 253, 264, 287, and 297 K) for the region 600-1900 cm(-1) at 0.03 cm(-1) instrument resolution, by Fourier transform infrared spectroscopy. In addition, air-broadened spectra of HFC-32 vapour have been recorded at 203, 251, and 297 K at pressures of 5, 20, and 100 kPa air. Copyright (C) 1996 Elsevier Science Ltd. [References: 13]
