The Kratky-Porod wormlike chain is extended to a stiff chain model with threecharacteristic lengths by taking the continuous limit of a chain composed ofhindered-rotating bonds with fluctuating bond angles. The limiting results areclassified into four cases depending upon whether these three characteristiclengths possess their imaginary parts and whether they are degenerated or not.The persistence vector and chain dimension of this continuous limit modelindicate that the model is statistically equivalent to a superposition of threeKratky-Porod chains with different persistence lengths and chain directions,when the three lengths are all real and different. When two of the lengths areconjugate complex, the model shows the rotation of the direction of a componentKratky-Porod chain owing to the twisting freedom of the model, and when thelengths are degenerated, interaction effects of component Kratky-Porod chainsappear.
