TY - JOUR ID - 31196 TI - ROTATIONAL ASSIGNMENT OF NEW BANDS IN THE NO , EXCITATION SPECTRUM IN THE SPECTRAL RANGE OF 15600 cm TO 15633 cm JO - Journal of Sciences, Islamic Republic of Iran JA - JSCIENCES LA - en SN - 1016-1104 Y1 - 1994 PY - 1994 VL - 5 IS - 3 SP - EP - DO - N2 - Sub-Doppler excitation spectroscopy in a collimated cold supersonic beam of 5% NO seeded in argon has been performed with a spectral resolution down to 10 MHz for four vibronic bands within the perturbed B ?X A system of NO . The rotational temperature of about 15 K achieved by adiabatic cooling allows the separation of closely lying vibronic bands which overlap in absorption spectra taken at room temperature and which therefore could not be iden$- fied from the broad band excitation measurements UR - https://jsciences.ut.ac.ir/article_31196.html L1 - https://jsciences.ut.ac.ir/article_31196_4fcdf5a0e160e7e18ccff41295b909ea.pdf ER -
