▎ 摘　　要

Tetralayer graphene has recently become a new addition to the family of few-layer graphenes with versatile electronic properties. This material can be realized in three distinctive stacking configurations for which we de-termine spectroscopic signatures in angle-resolved photoemission spectroscopy, dynamical optical conductivity, and Raman spectra of interband excitations. The reported library of spectral features of tetralayer graphenes can be used for the noninvasive identification of the stacking order realized in a particular film.
