Notes:
When an anisotropic ensemble of isolated atoms or molecules absorbs radiation from a polarized laser beam and the resulting fluorescence is collected independent of wavelength (1+1 unresolved LIF) with optional polarization analysis, the moments of the spatial distribution of the angular momentum J of the initial state in the ensemble may be determined. Previously, work by A. C. Kummel, G. O. Sitz, and R. N. Zare [J. Chem. Phys. 88, 7357 (1988)] correctly derived what possible moments can be found when cylindrical symmetry is present. This work shows that several additional alignment moments, not mentioned in KSZ, can be found in ensembles having noncylindrical symmetry.
