Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
Question
Transcribed Image Text:c)
In a horizontal radiationless transition, the extent of overlap of the lu functions
(probability distribution) of the initial and final states is the primary factor
controlling the rate of internal conversion and intersystem crossing. Molecule (a)
and molecule (c) of Figure 2 show the v = 0 vibrational level of the initial
electronic state and v 7 vibrational level of the final state. Molecule (b) of Figure
2 shows the v= 0 vibrational level of the initial state and thev =1 vibrational level
of the final state. Which one of the molecules (a), (b) or (c)) displays the strongest
fluorescence? Explain your answer.
