Thanks. Followup question: does the light source have to be a laser? I read on the Wiki that CV Raman demonstrated the phenomenon with sunlight. So would it be possible to just observe the reflected light from an object and determine the molecules on it that are lighting up? If so, can (someday) someone come with a Star Trek-style tricorder that you look through and figure out the molecular composition of an object? Maybe at a distance of 100 meters?
