6 sheets · 305 rows
The same reference, laid out for paper. Each sheet is a high-contrast table built to print black-on-white with the column headers repeating at the top of every page and the breaks falling between sections rather than mid-table — the one thing a reference page in a browser cannot give you at 1am with a problem set in front of you.
Where a source record carries no value — a reaction with no recorded mechanism subtype, an acid whose conjugate base is not named — the sheet prints not defined and a numbered footnote saying which field the data stops at. It never fills the gap with a plausible-looking value.

Every reaction in the library on one sheet, grouped by transformation — substitution, elimination, addition, oxidation, reduction, aromatic, carbonyl, pericyclic, rearrangement and coupling — with the substrate, the reagents that do the work, the product and the stated conditions. The sheet to put beside the problem set.
63 rows · landscape
What each reagent does and when to reach for it, grouped by role — reducing, oxidising, base, acid, catalyst, nucleophile, leaving group. Formula, function, the transformations it is used for, and the limits that catch people out in an exam.

The three tables you need next to a spectrum, laid out on one sheet: infrared absorptions with intensity and band shape, ¹H NMR chemical shifts by proton environment, and ¹³C NMR shifts by carbon environment. Each table keeps its own columns, because an IR band has an intensity and a shift does not.

The acidity ladder and the protecting-group cheat sheet on one page — the two things a synthesis problem asks for at the same time. Every pKa in the library with its conjugate base where the record names one, then each protecting group with what it protects and the reagents that put it on and take it off.
25 rows · landscape
Every functional group in the library grouped by family, with its general formula, polarity, and the IR, ¹H and ¹³C signatures that identify it. The sheet for working backwards from a spectrum to a structure.
25 rows · portrait
Every mnemonic and rule of thumb in the library, grouped by what it is for — mechanism, stereochemistry, reagents, spectroscopy and general strategy. The revision-week sheet.
What costs and what does not
Every reaction, reagent, functional group, pKa value, IR band, NMR shift, protecting group and mnemonic on these sheets is free to read on its own reference page — no account, no paywall, forever. A sample of each sheet renders for everyone so you can judge the layout before deciding. Premium unlocks the complete print-ready sheets and the print button.
