What is the meaning of selection rule related to UV spectroscopy?
The Selection Rules governing transitions between electronic energy levels of transition metal complexes are:ΔS = 0 The Spin RuleΔl = +/- 1 The Orbital Rule (Laporte)The first rule says that allowed transitions must involve the promotion of electrons without a change in their spin.The second rule says that if the molecule has a centre of symmetry, transitions within a given set of p or d orbitals (i.e. those which only involve a redistribution of electrons within a given subshell) are forbidden.Relaxation of the Rules can occur through:a) Spin-Orbit coupling - this gives rise to weak spin forbidden bandsb) Vibronic coupling - an octahedral complex may have allowed vibrations where the molecule is asymmetric. Absorption of light at that moment is then possible.c) π-acceptor and π-donor ligands can mix with the d-orbitals so transitions are no longer purely d-d.
Why are color blind people not allowed driving licenses?
Because they can't tell the difference between red and green.
What are true about Bohr's model of the hydrogen atom?
Electrons can exist only in certain allowed discrete energy states/ Photon absorption and emission are the result of transitions between energy states/ Electrons with more energy have orbits further from the nucleus

What is the difference between red and green cabbage?

What is the difference between 'forbidden' and 'prohibited'?

not allowed to come means you were dis-included allowed to not come means you were given permission to not attend
What is difference between Gal16v8a and GAL16V8b?
The Gal16V8B needs pull up resistors on the outputs. Will also provide sharper transitions because of the pull up resistors.
What is forbidden between Muslim couples?
If you mean sexually, anal sex is forbidden. Just put things where they belong. Foreplay, oral sex, massages, etc. are definitely allowed. This, of course, is all in the boundaries of marriage.
What is the difference between can and cannot?
