Raptim Research Interview Questions, Process, and Tips

UV principle refers to the use of ultraviolet light for various applications such as sterilization and disinfection.

• UV light is a type of electromagnetic radiation with a wavelength shorter than that of visible light.

• It is commonly used for sterilizing surfaces, air, and water by disrupting the DNA of microorganisms.

• UV light is also used in industries like healthcare, food processing, and water treatment for disinfecti

The fingertip region of IR spectroscopy refers to the portion of the infrared spectrum where unique vibrations of functional groups are observed.

• The fingertip region typically ranges from 1500-400 cm^-1 on the wavenumber scale.

• It is important for identifying specific functional groups in a molecule.

• Examples of important peaks in the fingertip region include C=O stretching at around 1700 cm^-1 and C-H bending at around

Prepare 1 N NaOH by dissolving 40 g of NaOH in 1 L of water.

• Measure out 40 g of NaOH using a balance

• Add the NaOH to 1 L of water in a suitable container

• Stir the solution until the NaOH is completely dissolved

• Check the pH to ensure it is at the desired level
