Millimeterhyphen; and submillimeterhyphen;wave spectrum and molecular constants of cuprous chloride

摘要

Monomeric cuprous chloride (CuCl) has been produced an an intermediate reaction product of copper and chlorine gas at 1000deg;K. Rotational transitions of63Cu35Cl,65Cu35Cl,63Cu37Cl, and65Cu37Cl have been measured in the millimeter and submillimeter wave region. Transitions have been observed in 7 different vibrational states and forJas high as 32rarr;33. Analysis of the data yields the following Dunham and equilibrium coefficients for63Cu35Cl:Y01= 5343.72266(100) MHz,Y11= minus;30.37285(120) MHz,Y21= 0.06021(46) MHz,Y31= minus;0.061(50) kHz,Y02= minus;3.89432(77) kHz,Y12= 0.00234(47) kHz,Y03= minus;0.0006220(10) Hz,Be= 5343.768(20) MHz, ohgr;e= 417.599(42) cmminus;1, ohgr;exe= 1.617(6) cmminus;1; for65Cu35Cl:Y01= 5284.98184(100) MHz,Y11= minus;29.87340(120) MHz,Y21= 0.05889(46) MHz,Y31= minus;0.059(50) kHz,Y02= minus;3.80917(77) kHz,Y12= 0.00227(47) kHz,Y03= minus;0.0006017(10) Hz,Be= 5285.026(20) MHz, ohgr;e= 415.297(42) cmminus;1, ohgr;exe= 1.599(6) cmminus;1; for63Cu37Cl:Y01= 5158.15294(100) MHz,Y11= minus;28.80453(120) MHz,Y21= 0.05610(46) MHz,Y31= minus;0.056(50) kHz,Y02= minus;3.62854(77) kHz,Y12= 0.00214(47) kHz,Y03= minus;0.0005594(10) Hz,Be= 5158.195(20) MHz, ohgr;e= 410.284(42) cmminus;1, ohgr;exe= 1.561(6) cmminus;1; for65Cu37Cl:Y01= 5099.41148(110) MHz,Y11= minus;28.31388(120) MHz,Y21= 0.05483(46) MHz,Y31= minus;0.054(50) kHz,Y02= minus;3.54636(77) kHz,Y12= 0.00208(47) kHz,Y03= minus;0.0005405(10) Hz,Be= 5099.453(20) MHz, ohgr;e= 407.941(42) cmminus;1. ohgr;exe= 1.543(6) cmminus;1.
