+ | Five or six lines are essentially unblended and have a sufficient signal-to-noise ratio, | ||
+ | two more lines are blended, and the combination of the contributions account nicely for the emission lines. | ||
+ | So the identification was deemed to be somewhat tentative in this line-rich survey. | ||
+ | From the estimate of the column density, one can derive a degree of deuteration per H atom of ~0.16, | ||
+ | compared to ~0.036 per H atom in the case of // | ||
+ | Such an enhancement of the degree of deuteration per H atom has also been seen for other | ||
