Spectroscopic Evolution {#res:spec}
=======================

The spectra of  at 10 phases from +7d to +143d are shown in Figure \[fig:spec\_all\]. The spectra are corrected for the recessional velocity of the host galaxy ($\sim$ $1567\pm3$ )[^6]. Spectral features are mainly identified as per previously published line identifications for IIP SNe [@leonard02; @pastorello04]. The two earliest spectra (+7d and +14d) show the blue continuum of blackbody emission and have broad P-Cygni profiles of ,  and  $\lambda$5876. The next two spectra (+54d and +60d) represent the mid-plateau phase and are marked by a decrease in the continuum and the appearance of more number of P-Cygni profiles for the permitted metallic (, ,, , , ),  $\lambda$7773,  D, and  IR triplet lines similar to other normal Type IIP SNe (see @roy11 and references therein). The spectra at phases +87d, +90d and +99d represent the end stages of the plateau and these are marked by a redder continuum and decreasing line widths of hydrogen lines. The +118d, +119d and +143d spectra represent the nebular phase having
