About

SolvatoChrom is a web tool for studying the influence of solvent parameters on dye photophysical characteristics.

With this service, you can perform:

• Simple Linear Regression (SLR) for all solvation parameters
• Multiple Linear Regression (MLR) for:
  • The four-parameter Catalán equation
  • The three-parameter Catalán equation
  • The three-parameter Kamlet-Taft equation

Statistical analyses are implemented using scikit-learn.
