+The //v// = 1 − 0, //P//(1) and //P//(2) transitions were detected near 3.5 and 3.6 μm, respectively, using the iSHELL spectrograph at the Infrared Telescope Facility on Mauna Kea. Their best source model reproduced the  //P//(1) flux very well, but underproduced the fluxes of the //P//(2) and rotational transitions.\\
