Structure Studies of Solutions of Large Organic Molecules. II. End-to-End Distances of Alkanes from C8− to C22−

End-to-end distances for a series of alkanes in the range C8− to C22− have been measured by the technique described in the preceding article. There appears to be good agreement with the theoretical values of the characteristic ratio 〈r2〉 / nl2 cited by Flory. However, there is evidence that solvent effects are present. These are discussed.
