Wavenumber to Pressure Conversion

Detailed Operation

Wavenumber Input

Input field in light mode Input field in dark mode

Enter the Raman wavenumber in cm⁻¹:

  • Valid range varies according to selected laser
  • For 785nm laser, negative values are accepted
  • Calculation is performed automatically

Automatic Validation

The app automatically verifies:

  • If the value is within the possible range
  • If it would result in valid pressure (0-500 GPa)
  • Shows clear messages for invalid values
