We compare and analyze a time series of spectral observations obtained during the first 30 days of evolution of SN 2007od with the non-LTE code PHOENIX . Despite some spectroscopic particularities in the Balmer features , this supernova appears to be a normal Type II , and the fits proposed are generally in good agreement with the observations . As a starting point we have carried out an analysis with the parameterized synthetic spectrum code SYNOW to confirm line identifications and to highlight differences between the results of the two codes . The analysis computed using PHOENIX suggests the presence of a high velocity feature in H _ { \beta } and an H _ { \alpha } profile reproduced with a density profile steeper than that of the other elements . We also show a detailed analysis of the ions velocities of the 6 synthetic spectra . The distance is estimated for each epoch with the Spectral-fitting Expanding Atmosphere Method ( SEAM ) . Consistent results are found using all the spectra which give the explosion date of JD 2454403 ( 29 October , 2007 ) and a distance modulus \mu = 32.2 \pm 0.3 .
