The emission spectrum from a fluorescent microdroplet is compared with theory for the first time. The spectrum of oriented surfactant molecules on a levitated microdroplet is found to be in good agreement with semiclassical theory of the interaction of whispering gallery modes with excited molecules. The orientation of these surface entities is estimated through this comparison.
