Kinetics of thermal geometrical isomerizations of three sets of isotopically labeled cyclopropanes followed by tunable diode laser spectroscopy

The tunable diode laser spectroscopy method is useful to calculate geometrical isomerization of labeled cyclopropane rate constants and offers several improvements over infrared spectroscopic method. These include enhanced resolution over a small fractional wave number range, permitting the distinctions between vibrational-rotational transitions due to stereochemically divergent labeled isomers.
