Abstract
New infrared absorption bands were produced in the spectra of single crystals of sodium and potassium azides by irradiation with ultraviolet light at $77^{\circ}K$. Identical absorptions could be produced when the azides were irradiated in KBr pressed disk samples. Using the latter technique, the irradiation bands produced in the isotopic species $NaN_{3}{^{14}}, NaN_{a}{^{15}}NaNN^{15}N, NaNNN^{15}, KN_{3}{^{14}}$ and $KNN^{15}N$ were observed and their growth and bleaching properties investigated. Discussions will be presented of the possible relationship of the defects which produce the infrared absorptions to radiation induced paramagnetic centers postulated from electron spin reasonance investigations.$^{1-3}$
