Abstract
Phase shift cavity ring-down absorption spectroscopy with a continuous lase r is used to measure the absorption coefficients and integrated cross-secti ons for the Delta upsilon = 6 C-H stretching overtones of C2H4, C2H6, C3H8, n-C4H10, and n-C5H12. The absorption spectrum is obtained by measuring the magnitude of the phase shift that an intensity modulated continuous laser beam experiences upon passing through an optical cavity. Sensitive absorpti on detection (10(-6) cm(-1)) on gas-phase samples is demonstrated. (C) 2001 Elsevier Science B.V. All rights reserved.
