Comments: The far uv absorption spectra of Cyclohexane, Cyclohexene, Cyclopentane, Cyclopentene and Benzene have been
measured between 45000 and 64000 cm-1.
Values of Oscillator Strengths:
cm-1		f-value (calculated from the area under the curve by the formula f = 4.32 x 10-9 Integral Edv)
45600 - 51200	0.01
51200 - 58100	0.19
58100 - 64300	0.20
The oscillator strengths of the first two bands of cyclohexene vapor (0.01 and 0.19, respectively) are slightly lower than those obtained 
for cyclohexene in n-heptane solution. In the latter case one smooth band with a smooth wavelength tail was observed with an oscillator
strength of 0.23 ± 0.05.
