Conformational properties of substituted alkanes in solution: terminal nitro functionalities

Measurements of the dielectric permittivity of nitrohexane and 1,12-dinitrododecane in nonpolar aromatic hydrocarbon solvents are presented. The measured dipole moment of nitrohexane is 3.31 D and that of 1,12-dinitrododecane is 4.5 D. The time-averaged equilibrium conformation of 1,12-dinitrododecane has an overall bend angle of approximately 100 degrees . Measurements were performed over the temperature range 25 to 50 degrees C. Details of the measurement technique are discussed.<
