Rotational excitation of singly and doubly deuterated formaldehyde induced by collisions with molecular hydrogen: Rate coefficients and pressure broadening

Angular expansion coefficients of the HDCO-H2 and D2CO-H2 potential energy surfaces are provided as a supplementary material for all intermolecular distances as indicated in the file name; all data contain five columns with l1, m1, l2, l, expansion coefficients v(l1,m1,l2,l) (in cm-1). The tensor ranks l1, l2 correspond to the orientations of HDCO (or D2CO) and H2, l is the tensor rank of the collision vector orientation satisfies the relation |l1 - l2| < l < l1 + l2, and m1 satisfy the relations m1 < l1.
