orthohydrogen meaning in Hindi

Examples

1. Parahydrogen is in a lower energy state than is orthohydrogen.
2. This is the T = 0 intercept seen in the molar energy of orthohydrogen.
3. At room temperature and thermal equilibrium, thermal excitation causes hydrogen to consist of approximately 75 % orthohydrogen and 25 % parahydrogen.
4. At room temperature, the proton spins of hydrogen gas are aligned 75 % of the time, resulting in " orthohydrogen " when they are.
5. The triplet orthohydrogen state has total nuclear spin I = 1 so that the component along a defined axis can have the three values M I = 1, 0, or  " 1.
6. Each orthohydrogen energy level then has a ( nuclear ) spin degeneracy of three, meaning that it corresponds to three states of the same energy ( in the absence of a magnetic field ).
7. From 1928 to 1933, Harteck was a staff scientist at the KWI f�r physikalische Chemie und Elektrochemie ( KWIPC ) ( Kaiser Wilhelm Institute for Physical Chemistry and Elektrochemistry ) located in parahydrogen and orthohydrogen.
8. Many physical and chemical properties of hydrogen depend on the parahydrogen / orthohydrogen ratio ( it often takes days or weeks at a given temperature to reach the equilibrium ratio, for which the data is usually given ).
9. The factor of 3 in the partition function for orthohydrogen accounts for the spin degeneracy associated with the + 1 spin state; when equilibrium between the spin isomers is possible, then a general partition function incorporating this degeneracy difference can be written as:
10. However, at the temperature of liquid hydrogen, not enough heat energy is available to produce orthohydrogen ( that is, the transition energy between forms is large enough to " freeze out " at this low temperature ), and thus the parahydrogen form predominates.
