Because he had chosen the absorption line of ammonia gas as the source of frequency, Lyon's first obstacle was measuring the inversion

transition frequency, or what Lyons called, in keeping with Thomson and Tait [2], the "vibration" [11], of the atoms inside ammonia molecules.

"The measurement of the

transition frequency has been improved by a factor of 1.4 to 10 compared with previous experiments.

For pis sample

transition frequency is 9.8 10-1 Hz.

It describes a fluid with a single

transition frequency, as described above in the theoretical results.

Dynamic modulus-frequency master curve at temperature 293 K is obtained based on WLF equation to characterize the dynamic modulus at frequency range from [10.sup.-6] to [10.sup.8] Hz, while the

transition frequency threshold value from glassy to rubbery state is gained in the master curve.

where [f.sub.nm] is the unperturbed

transition frequency. The splitting of the resonances obtained by the numerical resolution of the full Schrodinger equation (12) is in quantitative agreement with (16).

On the contrary, CPE25 addition initially decreased the transition point as compared with pure polymer but on average the behavior shifted to higher frequency values and the highest

transition frequency of 3.4 rad/s was observed at 30% CPE content, which would have resulted because of better miscibility of the phases.

Here, the

transition frequency between level [5.sup.2][P.sub.1/2] and level [5.sup.2][P.sub.3/2] is 2[pi]c x (12816.545 - 12578.950) [cm.sup.-1], i.e., 4.5 x [10.sup.13] [s.sup.-1].

Transitions from top to bottom between two fixed and adjoined textural layers in the entire area were summed, and the

transition frequency matrix (TFM) N was:
