What are the different vibrational modes in IR?
Symmetric and Asymmetric stretching, Bending (scissoring), Rocking, Twisting and Wagging.
What is the effect of hydrogen bonding on vibrational frequencies in case of IR spectroscopy?
Hydrogen bonding results in the broadening of the stretching frequencies of functional groups like -OH, -NH, -COOH etc.
What is the main principle of IR spectroscopy?
IR spectroscopy is useful in identifying functional groups in your sample. Many functional groups have specific absorption frequencies, so examination of IR spectra can tell you which functional groups are present (but not where they are structurally in your molecule). A table of common IR absorption frequencies are here: http://www.chem.ucla.edu/~webspectra/irtable.html Most of the time IR is used with NMR to identify a compound. IR can often be used independently to see if a reaction has worked (like if you are adding an azido group to your compound, you can use IR to see if your purified product has an azido absorption).
What is the traditional method of infrared spectroscopy?
Infrared spectroscopy (IR spectroscopy) is the subset of spectroscopy that deals with the infrared region of the electromagnetic spectrum. It covers a range of techniques, with the most common type by far being a form of absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify a compound and to investigate the composition of a sample. For further details, see the links to the left of this answer.
