Estimation of rotational temperature of 121Sb16O molecule

摘要

The (0,1), (0,0), (1,0) and (2,0) bands of e??μ a?’ e?‘? system of antimony monoxide have been excited in rf discharge tube source and photographed in the 9th order of a two metre plane grating spectrograph (PGS-2). Intensity records of the rotational lines have been obtained. The intensity measurements of e?‘? and e?‘? branch lines of the above four bands and e??? numberings are used to estimate the effective rotational temperature of the source emitting the spectrum of 121Sb16O molecule. It is concluded that 121Sb16O may be present in e??? type stars.
