✦ Synopsis

The axial symmeuy of the tensor density matrix elements created by the absorption of linearly polarised radiation is demonstrated. It is shown thar a full determination of the state multipoles of ;1 polarised array ir poz.siblc using 2 single cperimcntal geometry Laser excitation OF molecules invariably leads to the production of polarrsed excited arrays [l] which possess a distinctly non-uruformflfJ distribution. The treatment of laser-excited ensembles is conveniently handled within the framework of the excited-state density matrix, p_ Rather than deal with the individ-
