This paper is a brief overview to coherent anti-Stokes Raman spectroscopic technique and introduces thestrengths and barriers to its use all based on the interpretationof simple theoretical formulae. The use of theGaussian ultrashort pulses is highlighted as a practicalelucidatory reconstruction tool of coherent Raman spectra.The paper presents the integral formulae for coherentanti-Stokes and Stokes Raman scattering, and discussesthe closed-form solutions, its complex error function, andthe delay time formula for enhancement of the inferredpure coherent Raman spectra. As an example, the timeresolvedcoherent Stokes Raman scattering experimentalobservations are quantitatively elucidated.Understandingthe essentials of coherent Raman spectroscopy, therefore,promotes the importance of a number of experiments includingthe ones utilizing a broadband excitation with anarrowband delayed probing for successful backgroundsuppression
