Exciton absorption spectra of layered InSe and GaSe crystals electrochemically intercalated by hydrogen were investigated. It was found that the observed at T = 80 K non-monotonic shift of the exciton absorption peak n = 1 with growing hydrogen concentration x (here x is the amount of hydrogen atoms...
