    3. Requires Microsoft Windows 3.1 or latter and 14 MB free disk space (each program, 28 MB total). Recommend a 486/33 DX or faster and 8 MB RAM.

    4. These are very easy to use NMR shift prediction programs for 13C (CNMR) and 1H (HNMR). You draw a chemical structure and send it to the NMR routine. The program generates a spectrum from shift tables. The program includes proton decoupling, spectrometer frequency, spectral editing, integration and solvent peaks.

      4. Review: Van Bramer, S.E. Concepts in Magnetic Resonance, 1997, 9, 61-62.

      5. Assigns 13C chemical shift to structure drawn with ChemWindows. The user draws a chemical structure with ChemWindow and then the program assigns 13C chemical shifts based upon chemical shift tables.

      2. Demo version available from Softshell or Cherwell

      3. Windows version requires Win32s, Windows NT or Windows 95. Recommend a 486/33 DX or faster. Macintosh version requires 4 MB RAM, MacOS 6.0.5 or above a MC68020 (or higher) processor. A math co-processor is recommended. PowerMac version is available.

      4. This is an NMR spectrum simulator. It can simulate spectra for many different nuclei, import chemical structures and predict shifts (I tried 13C and 1H), you may also enter shifts and coupling constants in a table. Based on these shifts and coupling constants the program generates a spectrum.

      5. Hyper NMR.
        1. HyperCube Inc.; 419 Phillip Street, Waterloo, Ont. N2L 3X2, Canada; (800) 960-1871; Email:; Cost $995 commercial, $695 academic.

        2. Slideshow demo available from Hypercube.

        3. Requires 386 DX or faster PC with 4 MB RAM and Windows 3.1. Recommend 120 MHz pentium with 16 MB RAM. A Math Coprocessor (DX Chip) is required. Hyperchem or Mopac is needed to produce molecule files for input.

        4. Reviewed Anal. Chem. 67, 1995, 541A.

        5. A priori prediction of the NMR spectrum from the molecular structure. Imports Hyperchem (*.HIN) or Mopac Z-matrix (*.ZMT) molecular structure files. The user selects the NMR active atoms in the structure. The program calculates the NMR chemical shifts and coupling constants from the electronic structure of the molecule. The information is presented in tables or as a simulated spectrum. It is important to note that these spectra are calculated from the electronic structure, not from tables of chemical shifts. As a result this software is a very computationally intensive. Even modest size molecules require additional RAM and memory errors are common even with modest size molecules. The program will calculate 1H, 13C, 15P, 19F, and 31P NMR.

      6. NMR Analyzer. V 3.0.

        2. Download NMR_AN.ZIP (108k). Copy to directory and unzip. From Program Manager add nmr.exe as new program item. Requires VBRUN100.DLL (271k). Set your browser to save *.dll files and copy to directory.

        3. Requires Microsoft Windows 3.1 or latter. Recommend a 486/33 DX or faster.

        4. This program simulates the NMR spectrum for a system of up to 7 spins. The user enters chemical shift and coupling constants for the system, sets the spectrometer frequency, and the spectral linewidth. The program then calculates and displays a simulated spectrum.
