QNMR qNMR and Concentration determination: Improved usability, reporting, and many new features These new automatic deductions become very handy when assigning diastereotopic protons. (Note: this type of assignments deduction works only for multiplets and not for other spectral elements such as peaks, regions or integrals). Furthermore, this process works in the other direction: when assigning a HSQC multiplet, the program will automatically assign corresponding 1H multiplet even if the 1H spectrum has no multiplets. When manually assigning an atom from the molecule to a 1H NMR multiplet, the program will automatically deduce corresponding HSQC correlation even if the latter has no multiplets created. NMR Assignments Smarter manual assignments with 1H and HSQC NMR spectra.
