Hi guys,

Just a quick question. If IR light is unable to travel through an object, such as glass, if I were to image this object in  transmission or reflectance, will I just get noise??

Thanks heaps,

Astrid

It depends on your sample holder.  But in transmittance, yes, you will only see noise.  In reflectance or on an ATR instead of a cell, you may get a spectrum.  Unless something absorbs perfectly at all wavelengths, which doesn't seem likely to me. Cf. http://pubs.acs.org/doi/abs/10.1021/ac403412n
