摘要：

The angular distribution of scattered light is calculated for a rod consisting of three co-linear sub-units of variable lengths and densities of scattering centers. The general expression obtained is applied to the particular case of the muscle protein tnyosin, which had previously been shown to be a linear aggregate of three rod-like sub-units (meromyosins), two of which are identical. Within the experimental error the measured distribution is shown to agree with theory only if the two identical units (L-meromyosin) are arranged consecutively in the intact molecule.
