Area of Science:

  • Crystallography
  • Forensic Science
  • Materials Science

Background:

  • X-ray diffraction (XRD) is a powerful technique for analyzing crystalline structures.
  • Understanding the crystalline properties of illicit drugs is crucial for forensic identification and control.

Purpose of the Study:

  • To provide measured X-ray diffraction spectra for heroin and opium.
  • To determine the crystal system and lattice parameters of heroin.
  • To identify common additives in heroin samples.

Main Methods:

  • Acquisition of practical X-ray diffraction spectra for heroin and opium samples.
  • Detailed analysis of diffraction peaks to determine crystallographic parameters.
  • Comparison of sample spectra against standard spectra of pure heroin and known additives like sucrose.

Main Results:

  • The crystal structure of heroin was determined to belong to the orthorhombic system.
  • Lattice parameters for the primitive cell of heroin were precisely listed (a = 8.003, b = 14.373, c = 16.092 x 10(-10) m).
  • Sugar was identified as the main additive in the analyzed heroin samples through spectral comparison.

Conclusions:

  • The crystallographic data provides a reference for heroin identification.
  • The identification of sugar as a common additive offers insights into drug தயாரிப்பு (preparation) and trafficking.
  • X-ray diffraction is an effective method for the characterization and adulterant analysis of illicit drugs.
