For example, when this treatment is applied to CO 2, it is found that the C=O stretches are not independent, but rather there is an O=C=O symmetric stretch and an O=C=O asymmetric stretch: symmetric stretching: the sum of the two C–O stretching coordinates; the two C–O bond lengths change by the same amount and the carbon atom is stationary ...
The irreducible representation for the C-O stretching vibration is A 1g + E g + T 1u. Of these, only T 1u is IR active. B 2 H 6 has D 2h molecular symmetry. The terminal B-H stretching vibrations which are active in IR are B 2u and B 3u. Diborane. Fac-Mo(CO) 3 (CH 3 CH 2 CN) 3, has C 3v geometry. The irreducible representation for the C-O ...

"A symmetric tensor that results when a deformation gradient tensor is factorized into a rotation tensor followed or preceded by a symmetric tensor". Since a pure rotation should not induce any strains in a deformable body, it is often convenient to use rotation-independent measures of deformation in continuum mechanics .
Stretching can be dangerous when performed incorrectly. There are many techniques for stretching in general, but depending on which muscle group is being stretched, some techniques may be ineffective or detrimental, even to the point of causing hypermobility, instability, or permanent damage to the tendons, ligaments, and muscle fiber.

The pigeon pose is a static stretch Houlin highly recommended for post-workout. You’re on the ground with your front leg in a 90-degree bend at the knee with the back leg extended behind you ...
Defining crónica is difficult and contentious, as the genre is flexible, malleable, and mutating. It can be short or long; and, it can be poetry. [1] There are certain broad guidelines that identify and help recognize the genre.
With a stretching exponent β between 0 and 1, the graph of log f versus t is characteristically stretched, hence the name of the function. The compressed exponential function (with β > 1 ) has less practical importance, with the notable exceptions of β = 2 , which gives the normal distribution , and of compressed exponential relaxation in ...
