Abstract: Excitation processes in collisions of low-energy electrons (1–100 eV) with glutamine molecules in the gas phase have been studied. The optical emission spectra were measured in the wavelength range from 250–520 nm and it was found that, as a result of the decomposition of glutamine molecules, OH molecular emissions and some other molecular fragments are most efficiently formed. And excited hydrogen atoms are also detected. It was found that the excitation thresholds of molecular emissions are 10–12 eV, while the atomic lines of hydrogen are 13–15 eV. The energy dependences of the excitation of individual emissions from a threshold to 50 eV are also presented.

Keywords: electron, glutamine, excitation, fragmentation.
