摘要
We report the Fourier Transform Infrared (FTIR) spectrum of chlorobenzene (C6H5Cl) measured using synchrotron radiation and the ETH-SLS 2009 prototype spectrometer at the Swiss Light Source (SLS). The maximum optical path difference of these measurements was 11.8 m leading to a resolution of better than 0.0008 cm(-1). The spectra were taken at room temperature in the range 600-900 cm(-1). It was possible to analyze the in-plane mode nu(12) of A(1) symmetry ((nu) over bar (0) = 706.6686 cm(-1)) and the out-of-plane mode nu(10b) of B-1 symmetry ((nu) over bar (0) = 741.2240 cm(-1)) of (C6H5Cl)-Cl-35. In addition, the ground state constant Delta(K) of (C6H5Cl)-Cl-35 has been readjusted using combination differences (CD). (C) 2015 Elsevier Inc. All rights reserved.
