In the paper, the evolution of the spectra of the classic nova V1112 (Per 2020) is described based on the spectra from databases ARAS (R=9000-11000). The discussed spectra cover the period of the outburst. The comparative analysis results on the behavior of the profiles of the selected lines (Hα, Hβ, HeI l587.6 nm, NaID, and Fe II) with changes in the star's brightness during the outburst are presented. Using the diffuse interstellar bands (DIBs) at 578 nm, 579.7 nm, and 661.4 nm, visible in the high-resolution spectra, their equivalent widths were measured (for the 578 nm lines is  W=0.0402, for 579.7 nm is W=0.0140, and for the 661.4 nm is W=0.021), the interstellar extinction, the star magnitude ,MV=-8m.03 and the distance d= 4.5 kps to Nova Per 2020 were estimated.
       Based on the photometric data of the star, it was established that the light curve of the star belongs to the D class of light curves. From the spectrum of the star, it was found that Nova Per 2020 belongs to the classical FeII type Nova.
