iPTF13dbt (00:44:01.52, +41:32:01.3) is a nova in M31 recently discovered by iPTF (ATel #5341; see also ATel #5349, #5350 for ASAS-SN detections). We obtained a spectrum of iPTF13dbt with the Double Spectrograph on the Palomar 200-inch Telescope on Sep 4, 2013, 06:48 UT. It shows strong emission lines, including Balmer series, O I 7773, O I 8446, O I 9264, He I 6678, and Fe II bands between 4900A and 5500A. The FWHM of Halpha is approx. 2700 km/s. The spectrum confirms that iPTF13dbt is a classical nova.
