LASER STARK SATURATION SPECTROSCOPY OF V2 BAND OF CD3I
The QP(4) transitions of the ν2 band of 12CD3I, which lie close to the P(16) 10.4-μm CO2 laser line, have been observed by saturation spectroscopy using both an intracavity Stark cell, and a Shimizu-type multipass arrangement.

| Summary: | The QP(4) transitions of the ν2 band of 12CD3I, which lie close to the P(16) 10.4-μm CO2 laser line, have been observed by saturation spectroscopy using both an intracavity Stark cell, and a Shimizu-type multipass arrangement. Since both level crossing and Lamb dip signals can be seen using these transitions, they serve to illustrate both the uses of the two types of Stark cell, and also the differences between the two kinds of nonlinear signals. A simple derivation of the quadrupole matrix elements in the uncoupled basis is given. The dipole moments of the molecule in the ground and ν2 states were determined to be 1.6562 and 1.6523 D, from the measurements of the very sharp intracavity level crossing signals. © 1978. |
