We present spectroscopic analysis of 63 type II supernovae. We present preliminary results on correlations between spectroscopic and photometric properties, focusing on light-curve decline rates, absolute magnitudes and Hα lines profiles. We found the ratio of absorption to emission of Hα P-Cygni profile as the dominant measured parameter as it has the highest median correlation with all other parameters.
