✦ Synopsis
The circular dichroism spectrum of (-)-S-propyleneimine was recorded in the vapour phase and in hexane solution. SCF CI calculations of optical activity indicate that the absorption observed at ca. 50 000 cm-t corresponds to an n -3s Rydberg type transition. The possible nature of the next absorption is also discussed.

Fluorescence-detected optical-optical double resonance (OODR) spectroscopy is used to determine the rclatlve transition intensities from the 3pn CTI. r,'=O state to the n\*=6 supercomplex of NO.
