Transition metal dichalcogenides (TMDCs) are heavily studied due to their fascinating optical and electronic properties and possible technical applications. ReSe2 is a new material of the TMDC family. Unlike the well known MoS2 it grows in a distorted 1T structure. Therefore it has unique anisotropic properties which can be useful in future applications [1]. To develop a fundamental understanding of the optical and electric properties we studied the occupied electronic structure of ReSe2 with the help of angle-resolved photoemission (ARPES) and quasiparticle calculations.
