A comparison of to-vibrational transitions in the separated optical isomers of camphor is presented. An ir-rf double resonance experiment inside the laser cavity confirms that some to-vibrational transitions of camphor are efficiently saturated by 9.4 ~m CO 2 laser lines. Inverted Lamb-dips of d- and l-camphor have been measured for such transitions with a high accuracy by taking beats between the laser used to monitor the dip and a reference laser stabilized by 4 t~m fluorescence Lambdip. The transition frequencies of d- and l-camphor have been found to agree to within an accuracy of 1 X 10 -8.

Abstract
A comparison of to-vibrational transitions in the separated optical isomers of camphor is presented. An ir-rf double resonance experiment inside the laser cavity confirms that some to-vibrational transitions of camphor are efficiently saturated by 9.4 ~m CO 2 laser lines. Inverted Lamb-dips of d- and l-camphor have been measured for such transitions with a high accuracy by taking beats between the laser used to monitor the dip and a reference laser stabilized by 4 t~m fluorescence Lambdip. The transition frequencies of d- and l-camphor have been found to agree to within an accuracy of 1 X 10 -8.File in questo prodotto:
