Sensitivity

Sensitivity of CP-FTS


CP-FTS of OCS. Jet cooled spectrum of the J=1-0 transition of many different isotopologues of OCS around 12 GHz taken in natural abundance. Chirp excitation: duration 500 ns, bandwidth 1 GHz, power 20 W. Free induction decay (FID): Instantaneous bandwidth of 1 GHz taken in 107900 acquisitions of 100 μs each. Note the large dynamic range of intensities which demonstrates the high sensitivity of the method.
