==== 'RamanCrystalHunter' database (University of Padova) ====

  * //**Main page:**// [[https://www.fabrizionestola.com/rch]] 
  * //**Short description:**// The RCH software allows users to process their spectra using a variety of methods including, baseline corrections, smoothing, normalization, Raman shift calibration, add/subtract/replace functions, derivative determination, fitting and spectrum ID via comparison with the independent, on-board Raman database (RCHDB). 
  * //**Access to data:**// Only through plots from the software. Data cannot currently be downloaded.
  * //**Sample types:**// Minerals (1087), mineral inclusions in diamond (50), and synthetic materials (56)
  * //**Spectra types:**// Raman spectra over the Mid/Far-IR (mainly 50-2000 cm-1)
  * //**Search tools:**// Interface through the software. Allow to seach by best fit of part or all your spectrum, or by peak position (+ intensity and width) or through the alphabetic list of minerals.
  * //**Data format:**// currently no download of individual spectrum (v1.0): screen copy
  * //**Preview format:**// dynamic 
  * //**Metadata:**// Sample ID and name, locality (origin), source (provider), RIR (?), chemical composition, laser wavelength, sample orientation, reference
  * //**Metadata format:**// currently not downloadable (v1.0): screen copy
  * //**Download:**// unavailable
  * //**Notes:**// Currently (v1.0 / 2025) with a few bugs in the software, and no way to download a spectrum of the database but planned to evolve very soon.
