Adding your Annotations to a Spectrum

A document becomes more readable if you insert a comment, add a picture or a chemical structure, highlight a region with an arrow or a frame. The position of these notes can be defined in two alternatives frames of coordinates.

Peak Labels are defined in frequency (ppm) coordinates.
Document Notes are defined in window (paper) coordinates.

Any note can be moved from a set to the other. You can selectively hide one of the two sets or both.

Ways to Create a Note:

Choose Edit > Paste: if the clipboard contains text or a picture, iNMR will create, in the upper part of the window, a new note with it.

Drag text or a graphic from another window. Drag a note from a document to another.

Pick the writer tool and double click. Pick the quiver or the frame/bracket maker, then click and drag.

Open a graphic file: PDF, JPEG, PNG, TIFF... or open a molecular structure (mol file).
If you have installed the open source chemistry toolbox Open Babel, iNMR automatically leverages it to open structures saved in other file formats (like ChemDraw's).

Drag one (or more) of the recognized files from the Finder.

Universal Notes

There are two kinds of textual notes. Universal notes behaves normally, can contain any Unicode character and can have a style.

Latin Notes

Latin notes can contain ASCII characters only and are stored more efficiently. iNMR creates automatic subscripts (when a number follows a letter) and superscripts (when a number come before a letter and doesn't follow another letter). For example, if you write: 13C and CDCl3 they appear as ¹³C and CDCl₃. If you insert a space before and after the numbers, they are displayed normally.

Subscripts and Superscripts

To force iNMR into displaying (or not) a superscript (Latin notes only), enclose the superscript in curly braces, preceded by a caret. Use the same syntax for subscripts or for normal text. The symbols, in these cases, are the underscore and the equal sign, respectively.
For example: A^{1} 2_{B} C={3} will appear as: A¹ 2_B C3.
