Adding your Annotations to a Spectrum

A document becomes more readable if you add comments, pictures, or chemical structures, or highlight regions with arrows and frames. The position of these annotations can be defined in either of two coordinate systems.

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

Any note can be moved from one coordinate system to the other. You can selectively hide one of the two sets of notes or both.

Ways to Create a Note:

  1. Choose Edit > Paste: if the clipboard contains text or an image, iNMR will create, in the upper part of the window, a new note with it. With the Windows version you can only import text with this command. To import a picture under Windows, use method 4 or 5.
  2. Drag text, graphics, or existing notes from another window or document. This method works on the Mac version only.
  3. Pick the writer tool and double-click. Pick the quiver or the frame/bracket tool, then click and drag.
  4. Open an image file (JPEG, PNG, TIFF, etc.) or a molecular structure file (.mol).
    On the Mac you can select PDF files too. 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).
  5. Drag one or more supported files from the desktop.
  6. Pick the writer tool and click just once. The previous note will be duplicated.

Universal Notes

There are two kinds of textual notes. Universal notes support any Unicode character, can be styled, and can be rotated.

Latin Notes

Latin notes support ASCII characters only. iNMR creates automatic subscripts (when a number follows a letter) and superscripts (when a number comes before a letter and does not 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 to display (or not display) a superscript (Latin notes only), enclose the superscript in curly braces, preceded by a caret (^). Use the same syntax for subscripts and normal text. The symbols, in these cases, are the underscore and the equal sign, respectively.
For example, A^{3} 3_{A} A={3} will appear as: A³ 3A A3.
