Emission Band Spectra of Nitrogen. The Fifth Positive System

摘要

19 bands of the fifth positive system of nitrogen have been photographed in the second and third orders of a 21hyphen;foot grating spectrograph. Vibrational and rotational analyses gave the following results: (1)x1Sgr;gminus;thinsp;state:thinsp;Beequals;1.750,agr;eequals;0.0225,Deequals;6times;10minus;6,Teequals;aprime;plus;45284.7,ohgr;eequals;1910,ohgr;exeequals;20.7,reequals;1.168thinsp;A.thinsp;lpar;2rpar;thinsp;aprime;1Sgr;uminus;thinsp;state:thinsp;Beequals;1.480,agr;eequals;0.0164,Deequals;6times;10minus;6,Teequals;aprime;,ohgr;eequals;1530,ohgr;exeequals;12.0,ohgr;eyeequals;0.033,reequals;1.270A. An anomalous intensity distribution in thevprime;=0 bands was observed.
