What are red shift and blue shift in UV spectroscopy?
The solvent in which the absorbing species is dissolved also has an effect on the spectrum of the species. Peaks resulting from n ® p* transitions are shifted to shorter wavelengths (blue shift) with increasing solvent polarity. This arises from increased solvation of the lone pair, which lowers the energy of the n orbital. Often (but not always), the reverse (i.e. red shift) is seen for p ® p* transitions. This is caused by attractive polarisation forces between the solvent and the absorber, which lower the energy levels of both the excited and unexcited states. This effect is greater for the excited state, and so the energy difference between the excited and unexcited states is slightly reduced - resulting in a small red shift. This effect also influences n ® p* transitions but is overshadowed by the blue shift resulting from solvation of lone pairs.
Why they are several branches of science arises?
Their are several branches of science arises because it is healthy to have them and very intresting to study.

Glioma

What arises from lateral meristem activity?
secondary xylem and phloem.
How and why do the bonds between hydrogen and oxygen in water differ from bonds between hydrogen and carbon?
Hydrogen bonding exists between hydrogen and oxygen in water, becuase of the huge electronegativity difference between oxygen and hydrogen. This arises, due to the huge electron affinity of oxygen. Such interaction is not possible between carbon and hydrogen, as athe carbon is not as electronegative as oxygen.

What is the secondmost abundant element in the universe?
Helium is believed to be the second most abundant element in the universe, because the energy of most stars arises from the fusion of hydrogen to produce helium.
What does necessity arises mean?
Same as need arises.
what is Helium about?
helium is after haydrogen it means hygrogen is lighter than helium. now the question arises that "Q.1"why we use helium instead of hydrogen coz hydrogen is lighter than helium. Ans.1:hydrogen has 1 electron in its 1st shell and helium has it's complete shell with two electron. When we fill hydrogen in the baloon they form ionic bond... so it is used double...
What is the portion of the stem from which the leaf arises?
The portin of the stem where the leaf arises is called the node.
Arises from cranial and sacral nerves?
The Parasympathetic Division arises from cranial and sacral nerves.
How potential energy arises from the earth?
potential energy arises from the earth through gravitational pull.
What is the nutrient for the embryo that arises from the ovum called?
The yolk sac arises from the ovum to nourish the embryo.
What is the difference between elastomer and fiber?
The major difference difference arises on the basis of the forces... In Elastomers, the polymer chains are held together by weakest intermolecular forces while in fibers, the intermolecular forces are strong like hydrogen bonding.
What arises from right lobe but functionally are distinct?
the quadrate and caudate lobes arises from the right lobe but are functionally distinct
Why they are several branches of science arises?
Their are several branches of science arises because it is healthy to have them and very intresting to study.
