31. Nitrous oxide supports combustion by releasing the dipolar bonded oxygen radical, thus it can relight a glowing splint. 32. Because the rotation is not instantaneous, dipolar polarizations lose the response to electric fields at the highest frequencies. 33. In this notation the DA reaction and the dipolar reaction both become a [ 4 + 2 ] cycloaddition. 34. Huisgen investigated a series of cycloadditions between the 1, 3-dipolar diazo compounds and various dipolarophilic alkenes. 35. Like other 1, 3-dipolar cycloaddition reactions, azomethine ylide cycloadditions can form endo or exo products. 36. Solomon equations are used to calculate the transfer of magnetization as a result of relaxation in a dipolar system. 37. H, H Karplus relationships have been parametrized by NMR cross-correlated relaxation rates and residual dipolar couplings. 38. Examples being the electron-electron repulsion, magnetic dipolar coupling, and total angular momentum-squared operators. 39. Alternatively, Earth's dipolar field could have been oriented such that the poles were close to the equator. 40. Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind.
