Area of Science:

  • Organic Chemistry
  • Spectroscopy
  • Materials Science

Context:

  • Thiourea derivatives are versatile compounds with applications in various chemical fields.
  • Infrared (IR) spectroscopy is a crucial technique for characterizing molecular vibrations and functional groups.

Purpose:

  • To synthesize and characterize eleven new thiourea compounds.
  • To assign fundamental vibrational frequencies using IR spectroscopy.
  • To elucidate the structural properties of the synthesized thiourea derivatives.

Summary:

  • Eleven novel thiourea compounds were successfully synthesized.
  • Infrared (IR) spectroscopy was employed to study the vibrational properties of these compounds.
  • Specific IR bands were assigned: the thiourea I band (around 1540 cm⁻¹) attributed to N-H deformation coupled with C-N stretching, another thiourea I band (around 1280 cm⁻¹) linked to C-N stretching, and the thiourea III band (around 110 cm⁻¹) identified as C=S stretching vibration.
