The two square-planar isomers of [PtBrCl(PR3)2] (where PR3 is a trialkylphosphene) have different 31P-NMR spectra as shown below. For this exercise, we ignore the coupling to 195Pt (I=1/2 at 33% abundance). One isomer (A) shows a single 31P resonance; the other (B) shows two 31P resonances, each of which is split into a doublet by the second 31P nucleus. Which isomer is cis and which is trans? Draw the structures of the two isomers.
Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).

IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
