  Mixture Analysis Tools for NMR Data

  • Advanced mixture analysis search tools for 1D NMR spectra
  

  The layout above displays a process to support the rapid identification of multiple components from a relevant database, or set of databases, in the NMR spectrum of a mixture. Here, the user can select any number of spectral hits from the DB, adjust their positions relative to the query spectrum, adjust individual scales, and change peak widths until as many hits as possible are identified, and the residual is as low as possible. When the cursor is hovering on "more info" on the Spectra Comparison dialog box, the software displays a tool-tip with a list of capabilities to manage spectra display in the search result series.

  

  Note that at any time it is possible to create Sum and Residual curves as separate 1D spectra for further inspection.

  When the user sees that the hit spectra displayed in the search result series explains all desired peaks in the query spectrum (for example, the residual curve for that component approaches zero) it is possible to transfer all multiplets, structures and assignments from the displayed hit (considered to be pure component spectra) to the query spectrum (press "Replicate and Close" button). Note that there is an option to tell the software how the components in query or mixture spectrum should be named (Replication Parameters).

  

  Shown above is a typical layout after replication. The query spectrum is active and contains multiplets with assignments from all transferred structures. The assignment to components is encoded by colors (adjustable in the table of components) of multiplet labels and integrals. The colors of "pure component" spectra which are original DB hits are the same as component colors in the Table of Components. The first component is always named as "Query" (user –editable) to account for possible unexplained signals.

  • Improvements in mixture analysis workflows for 1D NMR spectra
  • When a user has a spectrum of a mixture and knows which signals in it came from which compounds, the software enables the user to set signals and assign them to various components, along with structures
  
  • A "Pure Component Spectrum" can be created, including only those signals which belong to multiplets assigned to the appropriate component. By looking at the difference between the original spectrum and the sum of all pure component spectra, unexplained signals in mixtures can be quickly tracked.
  

  Data Analysis

  NMR features

  • Reference Deconvolution—use experimental peak shape to determine proper parameters for peak-fitting
  • "Staggering" integration—Define an integral range on spectrum, then define sub-ranges within original range
  • Users can monitor relative concentrations of several isomers or rotamers while keeping total signal normalized to the required number of protons
  • "Autoscale Zoomed Region" for spectral similarity searches, which prevents oversized peaks outside the search region from obscuring the search results
  • Improvements to DOSY analysis:
  • Calculate the diffusion coefficient over a spectrum range using the Brush tool, and evaluate DOSY profile. Quickly see the D values for signals of interest and evaluate the diffusion profile.
  • This profile is deemed "not optimal" due to a low dynamic range in the measurements
  
  • Calculate average slice over a user-selected region in the DOSY spectrum
  • Seamless workflow for DOSY experiments that were not automatically recognized
  • For cases when DOSY data was imported as a 1D series, the conversion is simplified

  • The solvent detection options have been expanded:
  • The "Create New Component" option works for 1D spectra and assigns a signal for each detected solvent or impurity to new component
  • If "Create Dark Region" has been checked, the same compound signals in 2D spectra get Darkregioned
  • "Apply to Project" directs the software to act on all spectra included in the project
  • Clearer visualization of calculated chemical shifts calculated by HOSE-code or Neural Net methods
  • Option to detect solvent signals in multiplet detection options

  • The decimal places for chemical shift and coupling constant in the table of multiplets are now remembered separately for ¹H, ¹³C, ¹⁹F, ³¹P and ¹⁵N nuclei
  • The Verify macro command (applicable to ¹H or ¹³C data) has been replaced by Verify1DNMR (¹H, ¹³C, ¹⁹F, ³¹P and ¹⁵N) for 1D spectra, which ensures that results are identical between scripting and the graphical user interface (GUI)
  • Reverse the order of spectra in a series
  • Display multiplets in the Table of Spectral Data using the chemical shift range instead of just standard multiplet format
  • Ignore dark regions in database/query spectra for Sum and difference curves
