76 Chapter 3 As T ∞, so T-0 = As T ∞, 0,so II 3-7. Generalize the results of Example 3-1 to the case of a spin-1 nucleus. Determine the low- temperature and high-temperature limits of (E). For a spin-1 nucleus, = 1, 0, or 1. Therefore = and We now apply Equation 3.14 to find B₂) = 1 + e + = 1+ 2 cosh Bhy Using Equation 3.20 for (E) gives = aß = 1 = = Below, graphs of sinh(x) and cosh(x) are presented for reference. 4.0 cosh x sinh x 3.0 (x)f 2.0 1.0 0 0.5 1.0 1.5 2.0 x As T ∞, so II II As T 0,so 0
