Abstract

We describe methods of Raman spectroscopy for resolving mono crystalline sucrose using vortex laser beam modes with circular polarization. Research up to this point has led to controversy as to whether beams carrying orbital angular momentum (OAM) are capable of interacting with chiral matter, but there is also a general lack of experimental or theoretical research into the interaction of vortex beams carrying OAM or vector beams with vibrational modes in matter. Our attempts to detect and measure interactions with sucrose in crystal form mediated by OAM have resulted in findings that indicate a worthy path for future inquiry.
