How things work in the world of Industrial Chemistry and Polymers is not so well understood in the outside world. Chemistry is a mystery and the subject mostly has a bad name in popular media. I am a Ph.D. in Experimental Polymer Chemistry with decades of lab and managing experience in Industrial R&D in three countries. I thought to share the various learnings and exciting experiences.

In first part of the series we learnt how solutions of Schrodinger’s equation throws out various quantum numbers which define orbitals. In the second part we learnt about radial probability distribution of these orbitals, its effect on their energy levels and electron fill up sequence of any atom. In this last part we will focus on shape and directional aspects of orbitals ..read more

One common issue that we learn in college physics is that we think from De Broglie equation we can get wavelength of matter wave. But reality is that its all theoretical. So how can we arrive to some analytical methods to define an atom ..read more

In the previous article we learnt that atom can exist in specific energy levels. Bohr model could predict atomic spectra of Hydrogen. But it could not explain why in certain experiments matter behaves like a radiation, i.e, it can exhibit diffraction, just like regular light ..read more

Practicing organic, pharma, polymer and to an extent inorganic chemists keep a wide distance from the wavy world of quantum mechanics and the wave-particle duality of atoms. This distance keeping probably stems from two facts ..read more
