a Monopole positions are at the atomic centers. The monopole charges given here are in units of 10-10 esu. The monopole charges were calculated from a PPP calculation on indole using the Nishimoto-Forster variable-b parameters (K. Nishimoto and L. S. Forster, Theor. Chim. Acta 3, 407-417 (1965); 4, 155-165 (1966)).

a Because of the plane of symmetry, the z-component of the Ñ matrix element and the x, y components of the (r x Ñ) matrix element are zero. The x axis of the indole ring is directed from Ce2 toward Cd2. The y-axis is perpendicular to this and in plane such that Cd2 has a positive y coordinate. The origin is at the center of the Ce2-Cd2 bond. The transition parameters are taken from Woody (Eur. Biophys. J. 23, 253-262 (1994)).
