Color Center Laser-Microwave Double Resonance Spectroscopy of the nu1 Vibrational State of HCCF
Rotational transitions of fluoroacetylene in the nu1 (CH stretch) vibrational state have been observed by the laser-microwave double resonance technique using a color center laser as a radiation source in the 3 &mu;m region. The rotational constant and centrifugal distortion constant in the nu1 state were determined to be 9684.310(16) MHz and 2.68(62) kHz, respectively, where the uncertainties given in parentheses correspond to 2.5 standard deviations.
