## Description

Description of the supplementary materials for "Hyperfine structure of rovibrational quadrupole transitions in HD" by H. Jóźwiak, H. Cybulski, P. Wcisło The list of all hyperfine components of all rovibrational quadrupole transitions in HD is given in the Linelist-HD.zip archive, which contains 459 Linelist-branch-v’-v.dat files, respectively. Label branch corresponds to O, Q or S and v and v’ denote the initial and final vibrational quantum numbers, which describe the vibrational band. Each file contains a list of all rotational quadrupole lines, written in the manner described in Sec. 4.1. We remind that the transition frequency of the rovibrational transition (as well as its uncertainty) is obtained from the H2Spectre code of Czachorowski et al. [40] and Komasa et al. [1]. A list of hyperfine levels of all bound states in the six isotopologues of hydrogen is provided in the HyperfineSplittings.zip archive. The archive involves seven folders which contain HF-splittings-X-vY.dat files, where X denotes the symbol of the isotopologue (oH2, oD2, pD2, oT2, HD, HT and DT) and Y denotes the vibrational quantum number. The format of each file corresponds to the one discussed in Sec. 4.2.
