In chemistry, van der Waals strain is strain resulting from van der Waals repulsion when two substituents in a molecule approach each other with a distance less than the sum of their van der Waals radii. Van der Waals strain is also called van der Waals repulsion and is related to steric hindrance. One of the most common forms of this strain is eclipsing hydrogen, in Alkanes.

Famous quotes containing the words van, der and/or strain:
“My position is a naturalistic one; I see philosophy not as an a priori propaedeutic or groundwork for science, but as continuous with science. I see philosophy and science as in the same boat—a boat which, to revert to Neurath’s figure as I so often do, we can rebuild only at sea while staying afloat in it. There is no external vantage point, no first philosophy.”
—Willard Van Orman Quine (b. 1908)
“Under the lindens on the heather,
There was our double resting-place.”
—Walther Von Der Vogelweide (1170?–1230?)
“Realistic about how much one person can accomplish in a given day, women expect to have to make some trade-offs between work and family. Families, however, have absorbed all the stress and strain they possibly can. The entire responsibility for accommodation is taking place on the home side of the equation.”
—Deborah J. Swiss (20th century)
