Equal-Legged Position

As in the case of the acid, there is a region in equilibrium with excess undissolved free base, here at high pH values and a region with high and constant solubility at low pH values. An analogous set of equations applies for the two legs of the theoretical pH solubility profile (equations (11) and (12)), whereas for the position of pH ax. equation (10) is equally valid for bases. 

The line positions for each /eg are not centred at the field Bq corresponding to the g-factor, but are displaced as shown in the stickplot of Fig. 3.5 for a radical with a large hyperfine coupling of six equivalent I = V2 nuclei (data are for C3F6 in Chapter 5) with effective nuclear spin values, /eff = 0, 1, 2, and 3 which occur 5, 9, 5 and 1 times. The 2 leg +1 hyperfine lines for a specific value of Lg > V2 are not equally spaced but the line splittings increase towards higher fields. The... 

The L network is shown in Fig. 13.39 The loaded Q of the networkis determined from Equation 1. Equation 2 defines the shunt leg reactance, which is negative (capacitive) when 9 is negative, and positive (inductive) when 9 is positive. The series leg reactance is found using Equation 3, the phase shift via Equation 4, and the currents and voltages via Ohm s law. Note that R2 (the resistance on the shunt leg side of the L network) must always be greater than An L network cannot be used to match equal resistances, or to adjust phase independently of resistance. 

The primary cooling system consists of a reactor vessel, three IHX vessels, three pump vessels and reverse-U shaped piping to connect these vessels. The reverse-U shaped piping reduces the required installation space. The vessels have free coolant surfaces and the cover gas is maintained at equal pressure by inter-connecting pipes. The coolant surface level in the IHX vessel during operation is lower than that in the reactor vessel due to the pressure loss in the hot leg piping. The cover gas pressure is about 0.9 atg in order to maintain positive pressure at the hipest point of the primary piping.
