  • Resize (distributed with Flot)
  • Selection (distributed with Flot)
  • Axis labels
  • Labels ( Modified by NIST for use in this application)

Additonal code used was developed at NIST: jcamp-dx.js and jcamp-plot.js.

Use or mention of technologies or programs in this web site is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it intended to imply that these items are necessarily the best available for the purpose.

Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments. More information on the manner in which spectra in this collection were collected can be found here.

Notice: Concentration information is not available for this spectrum and, therefore, molar absorptivity values cannot be derived.
