We present the second part of the review of spectroscopic observations of Mira variables in the optical and near infrared. The role of various structures (atmosphere, envelopes) in the formation of the optical spectrum is estimated. The thickness of the molecular layer that creates the observed effects of distortion of the emission spectra is estimated based on two model approximations. Assuming that a significant part of the optical spectrum is formed in the circumstellar envelopes, the known photometric and spectroscopic effects are discussed.
