The US National Institute of Standards and Technology is a good source. The following image show absorbance between 2.5 and 32 $\mu$m. For wavelengths shorter than 2.5 $\mu$m, other sources (less reliable) suggest that there is no significant absorption bands. enter image description here The original data in ASCII JCAMP-DX format can be downloaded here.

  • $\begingroup$ @bpl1960 I'm glad it was useful. It was the infrared absorption spectrum what you were looking for? If this solved you question feel free to accept the answer unless you want to encourage other answers for a while. $\endgroup$ Mar 16, 2018 at 20:26
