National Science Day Talk

  Abstract From Raman to the Future: Women Powering India’s Technological Rise The modern journey of Indian science found its global voice when C. V. Raman discovered the Raman Effect in 1928 - a breakthrough that revealed how light interacts with matter and earned India its first Nobel Prize in science. That discovery was born from simple curiosity - a question as profound as “Why is the sea blue?” From that moment, Indian science began its ascent on the world stage. Nearly a century later, that same spirit of curiosity has evolved - from understanding light scattering to engineering metal–organic frameworks, nanomaterials, and advanced energy systems. The scale has shifted from the visible to the nanoscale, but the ambition remains the same: to explore, innovate, and transform. Today, women scientists across India are at the forefront of this transformation. Leading breakthroughs in nanoscience, battery materials, renewable energy, and sustainable technologies, they repre...

Linear Triatomic Molecule: Modes of Vibration

Image
  Normal Modes of Vibration of a Linear Triatomic Molecule Normal Modes of Vibration of a Linear Triatomic Molecule We consider a linear triatomic molecule consisting of three atoms arranged in a straight line. The two outer atoms have equal mass $m$ , while the central atom has mass $M$ . The atoms are connected by identical springs of force constant $k$ . Let $x_1$, $x_2$, and $x_3$ be the small displacements of the three atoms from their equilibrium positions along the line of the molecule. Assumptions To simplify the analysis, we make the following standard assumptions: The oscillations are small . The restoring forces obey Hooke’s law . The forces are linear functions of displacement. The resulting motion is simple harmonic . Under these assumptions, the problem of molecular vibration reduces to a problem in linear algebra . Kinetic Energy of the System The total kinetic energy of the system is the sum ...
