What Experimental Evidence Led to the Development of Quantum Mechanics in Chemistry?

The study of quantum mechanics in chemistry changed a lot because of some important experiments. Let’s break them down:

  1. Blackbody Radiation: Scientists couldn’t figure out why heated objects, like a blackbody, gave off light in certain ways. Then, Max Planck suggested that energy comes in small pieces called "quanta." This idea helped explain the strange patterns of light.

  2. Photoelectric Effect: Albert Einstein showed that light can knock out tiny particles called electrons from metal. This was a big deal because it proved that light acts like both a wave and a particle.

  3. Atomic Spectra: When we heat certain elements, they shine light at specific colors or wavelengths. Niels Bohr created models that used these fixed energy levels to explain the special light patterns we see, known as atomic spectra.

All these experiments taught us that the way atoms and molecules behave is controlled by the rules of quantum physics. These rules are different from those of classical physics, which helped shape modern chemistry.
