In the previous chapters, we explored the concept of electron spin. We began by introducing the idea of spin and then clarified that electrons do

181. Spin Multiplicity (1).
In this post, we are going to learn an important concept in photochemistry—spin multiplicity. This concept plays a critical role in understanding how molecules behave
180. The electron spin (2).
In the previous post, we familiarised ourselves with the concept of electron spin. We learned that spin is an intrinsic property of an electron –
161.LAWS OF PHOTOCHEMISTRY (7).
In the previous post we studied the following equation for Beer – Lambert’s law – We understood that if we decide the intensity of incident
120 .Cyclobutadiene and benzene.
We learned in detail how HMO theory explains the structure and aromaticity of benzene in previous posts. In this post let us compare benzene to
119.Frost Musulin diagram/ Polygon Method.
\ This is a very useful mnemonic device for quickly setting down molecular diagrams for cyclic systems. A Frost circle is a simple diagrammatic method
96. Metallic bonding (2).
As discussed in the previous post, the free electron gas model was not infallible. Almost 30 years after the electron gas model was proposed, quantum
27. Quantum Numbers.
In the last post, we saw how quantum numbers were introduced to understand the structure of the atom. These quantum numbers describe all the necessary
24. The Bohr Model (2).
In this post, we continue our discussion on the Bohr model and study its applications and implications. In the earlier post, we discussed how Neils
23. The Bohr Model (1).
In this post, we shall start talking about another great physicist whose contribution to the atomic theory is unparalleled – Niels Bohr. Niels Bohr was born
21. History, Discovery of Electron.
With this post, we start a long discourse on a fundamental topic at the core of Chemistry and the understanding of the whole universe – THE
16. Accuracy and Precision.
We start this post with the introduction of two new parameters in error analysis namely – ACCURACY & PRECISION. ACCURACY PRECISION To understand these concepts let
