ElViS – Electronic and Vibrational Spectroscopies


To enhance the processing of electronic and vibrational spectroscopic techniques data, Mnova 15 endows the PLS based baseline correction tool (IarPLS) with a button to automatically compute a near-optimal value of its asymmetry parameter.








Additionally, three new Normalization Processing modes, i.e., Largest Peak, Integral and Vector Length have been integrated. These two key features contribute to a significant upgrade for our plugin, ElViS. The aim is to simplify the baseline correction process, streamline your workflow, and provide a rapid method for normalizing data to address quantitative issues.

Mnova ElViS supports the most frequently used data [file] formats for these analytical techniques, including import and export of single and multi-column matrix-like spectra (i.e. ASCII XY and XYY, as .txt or .csv files). 

  • SPC (Galactic) 
  • OPUS (Bruker) 
  • Single and multi spectrum SPA and SPG (Omnic) 
  • Perkin Elmer blocked structured (*.sp) 
  • ASCII (XY and XYY) 

This first version of the software allows manual and automatic peak picking as well as Data Analysis of stacked/arrayed spectra.

Main Processing Features:

  • Multiplicative Scatter Correction
  • Probabilistic Quotient Normalization
  • Baseline correction, both automatic (AsLS) and/or tailored (Multipoint Baseline Correction)
  • Several Smoothing techniques such as Savitzky-Golay, Exponential, etc.
  • Normalization and Standard Normal Variate (SNV)
  • Derivatives
  • Units conversion Absorbance to/from Transmittance
