Nuclear Magnetic Resonance solvent signals (NMRss) is useful for seeing if a signal is due to a common impurity or solvent.
How to use NMRss
- Select the solvent in which the NMR spectrum was obtained by tapping the solvent name > select a solvent. The first line displays the residual solvent signal(s) and the multiplicity of the signal(s).
- Toggle between proton or carbon nucleus by tapping ¹H/¹³C - the nucleus that is displayed is the currently selected one.
- A list of the solvent names, shifts, signal identities, and the multiplicities (with coupling constant where appropriate) is displayed.
- To more easily find potential matches for a given signal, a chemical shift range can be defined using the ‘from’ and ‘to’ boxes. Tapping ‘search’ will then highlight any shifts within the defined range.
- The order of the solvent signals can be changed by tapping the ‘order’ button and selecting an option.
- Both a dark and a light theme are available:
android < Q: tap the theme icon in the top right to toggle dark/highlight
android > Q: the theme is matched to the global settings of the phone
iOS < 13: tap the theme icon in the top right to toggle dark/highlight
iOS > 13: the theme is matched to the global settings of the phone
- The default solvent on opening the app can be set:
android: the last used solvent is set when the app opens
iOS: the last used solvent is set when the app opens
* The order of ‘default’ is that which matches the classic paper that most research chemists (and likely everyone who finds their way to this page) are familiar with: Organometallics, Vol. 29, No. 9, 2010.
