2013 June UGC NET NTA/JRF Previous Years Solved Forensic Science Paper 2 And Answer Key

1. The ‘fingerprint’ region of IR spectrum can be subdivided into the following except:

  1. 1500 – 1350 cm-1
  2. 1350 – 1000 cm-1
  3. Below 1000 cm-1
  4. Below 500 cm-1

Answer and Explanation

Answer: (4) Below 500 cm-1

The fingerprint region (infrared spectrum) ranges from 1450 – 500 cm-1 and this region has an almost unique spectrum for a compound and that why they are called to be the fingerprint region.

2. The ‘magic angle’ of NMR is at:

  1. 90 degrees
  2. 54.7 degrees
  3. 120 degrees
  4. 60.8 degrees

Answer and Explanation

Answer: (2) 54.7 degrees

In medical uses, at an angle of 54.7°, the z-component of the dipolar field is minimized which helps in imaging certain tissues that are highly structured especially tendons, cartilage, and peripheral nerves.
However, in the laboratory, Magic angle spinning (MAS) is used in solid-state MR spectroscopy where the sample is placed in an air-turbine device with an angle of 54.7° w.r.t magnetic field and spun at rates up to 70 kHz. And this setting helps in determining molecular structures of the highly structured compounds.

-> Bolometer is a detector to detect light in the far-infrared.
-> A photovoltaic cell or photomultiplier tube is used in visible spectrophotometry to detect the absorption of photons results in the emission of an electron from the sample.
