We have noted typographical errors in Table V of the published article.1 Specifically, the values of the angles φHχH for the XH2 species in both the (3B1) and (1A1) states were incorrectly reported as half of the correct values. The values of the same angles for the XH3 and XH4 species were reported correctly. The table with the corrected values is below.

TABLE V.
