(old?) spectroscopy analysis notation

[Aroldo]

Hello,

I've been studying spectroscopy in organic molecule and I came across an old data from 1934.

280(5b)(k,i±e), 297(1vd)(e), 354(1vd)(k,e),
378(1vd)(k,e), 398(Ovd) (e), 426(1vd)(k,e),
766(Ovd) (k,e), 807 (Od) (k,e), 817 (lb) (k,e),
842(1vd)(k,e), 862(2)(k,e), 878(3)(k,e),

This is a piece of the table for Octane. You can find it on the article: The Journal of Chemical Physics 9, 295 (1941); doi: 10.1063/1.1750899.

I couldn't identify this notation, and I am stuck on it.
Do you know where I can learn about this notation?

Thank you.

Why don't you try using Latex for writing equations?

Thanks for your replay.

This is not an equation. This is a table from the cited article, which I have no ideia what it is about.
