I am looking into the possibility that spectroscopically usable infra red emission can be generated by an electron beam. I can melt plastic and dehydrate minerals with beam at 50 nA so I assume that I am generating heat a infra red spectra. Dr. George Rossman is a leader in infra red and Raman spectroscopy and says he is not aware of IR emission from the excitation volume of a probe spot. Looking for any thoughts on this. Bart Cannon
