What are advantages of Attenuated Total Reflectance (ATR) sampling in IR over Beam Through Sample sampling?
What region of an IR Spectrum (give a range in wavenumbers) is most useful for distinguising between isomers that contain the same functional groups?
Are the characteristic vibrations for functional groups such as carbony groups (aldehydes,ketones,etc) and alcohols (RO-H) stretching vibrations or bending vibrations?
