This App has many functions which are very useful and convenient for both new NMR users and experienced NMR users.
The functions are grouped in four tabs
1. The Shifts tab: it contains 1H, 13C, 19F, 31P, 11B, 15N, and 29Si chemical shift information for different chemical functional groups. The chemical functional group can also be searched to highlight its chemical shift.
2. The Solvents tab: it contains 1H, 13C, coupling constant, boiling point, melting point information for deuterated solvents. It also contains 1H and 13C chemical shifts of protonated solvents in common deuterated solvents. It allows users to search the interested 1H or 13C chemical shifts in the selected deuterated solvents, which can help the NMR user to know the possible impurities.
3. The Isotopes tab: It shows the NMR isotopes in the chemical periodic table. For NMR active isotopes, it will show all NMR related information, such as natural abundance, spin quantum number, magnetic moment,chemical shift reference, etc. It can also show the Larmor frequency at different field.
4. The Tools tab: it has three functions. The first one is the recycle delay calculator. It calculates the recycle delay according the pulse flip angle (30 degree and 90 degree)based on the given T1 relaxation time. The second one is the NMR thermometer. It calculates the sample temperature when neat methanol/ethylene glycol/methanol-d4 is used for probe temperature calibration. The third one is the NMR dictionary which explains the frequently encountered NMR terms.

Note:
1. NMR Pro is an upgraded version of the previous NMR Assistant.
2. While NMR Pro has made every attempt to ensure accurate information in this App, NMR Pro takes no responsibility for the accuracy, completeness and reliability of the information provided.
