Transitions for the first four vibrational states have been observed in near zero electric field and zero magnetic field. The observed rf transitions exhibit a natural line width of 2.5 kHz. The quadrupole coupling constants for the two nuclei have been measured. We find $(eqQ)Na= -4072 \pm 5$ kHz in $v=0$ with a decrease of about 0.9% per vibrational state. For iodine, we find $(eqQ)_{t} = -262,140 \pm 5$ kHz in $v=0$ with an increase of 1.3% per vibrational state. These values are in minor disagreement with earlier $measurements.^{1.2}$ The constants for the excited vibrational states have been determined with less precision because fewer transitions were observed. en_US dc.format.extent 154492 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE RADIO-FREQUENCY SPECTRUM OF SODIUM IODIDE. en_US dc.type article en_US
