User:Tweenk/Infrared bands table

A draft version of a new infrared spectroscopy correlation table. It is sortable on the bond column using Hill ordering and on the wavenumber. Later some meaningful sortkey may be added to the Group column (e.g. hydrocarbons, carbonyl compounds, amines, etc.), and a more useful sortkey added for the Type column.

At this point the table is about 50% done. There are missing entries for heteroatom vibrations (B, Si, P. S, X, etc.) and heterocyclic ring vibrations, but the part for ketones is fairly comprehensive.
