Sample spectrum for the frequency range 335.3–335.45 GHz in the rest frame of each peak to indicate the diversity of these sources. G35.03 and G35.20 A do not appear to have any absorption features (in this range), but it is notable that the lines for these two sources are broader. The deuterated water (HDO) emission line at 335.396 is especially strong in B3, double peaked in G35.20 A, possibly has two velocity components in B2, and is either very weak or offset by several km s-1 in G35.03.
