Vibration-rotation structure in absorption bands for the calibration of spectrometers from 2 to 16 microns

Su ita ble ba nd of co mmon "a 'es have bee n tabulated and remeasured wh ereve r I\ ecessary from 2 to 16 microns to obtain a n accuracy of a bou t 0.03 cm-L t hroug hou t the re"ion an d to provide good calibrating poin t at fr eq uent intervals. So me 600 rotation-vibration l in es ar e illustrated in 20 spectrograms a nd wave numbers are listed in co mpa nion tables wi t h considerable in te rco mpa rison with worthy d ata obtain ed in other labo rato ri es. The a bsol'potion bands were remeasLIl'ed o r calibrated by usin g eith er a prec isely graduated gratin g circle or stal rd ato mi c lin es with t he frin ge system form ed by a F a b ry-P erot interf erometer . Characte ri stic featnres of t he individual ba nds are d iscu ssed bri efly and refere nces to other publi cations are g iv en . Th e su bstances used fo r calibration in clud e H 2 0, CO" CO, H Cl, HBr, N H 3, C2H2, CH., N2 0, a nd polysty rene film .
