| The relative strength of radar reflectivity is tabulated by sigma, for discrete objects, and by sigma nought for natural terrain surfaces. |
| It is all the way between ± one sigma of the asymmetric red circles wing, observationally undiscernible. |
| The alkene carbon-carbon double bond is made from two sp trigonally hybridized carbons, where one of the carbon-carbon bonds is a sigma bond and the other is a pi bond. |
| The triple bond is composed of one sigma bond from overlap of sp hybrid orbitals, and two pi bonds, from overlap of two sets of p orbitals. |
| At the same time, strain in the Pt N sigma bond framework often results in low-lying d d excited states that effectively quench the emission. |
| The log power of activity in delta, theta, alpha, sigma, and beta bandwidths was computed. |
