| Abstract: | The pressure dependence of coherent dephasing time T2 has been determined by investigating transient emission signals of molecular gas samples, following pulsed microwave excitation. Experimental results on cyanoacetylene (HCCC15N), deuterated fluoroform (CF3D) and 3,3,3-trifluoropropyne (CF3CCH) are reported for the pure gas and also for mixtures with H2 and He for rotational transitions in the frequency range from 5.8 GHz to 19.6 GHz. |
