Self-induced frequency lineshifts of NH 3 in the 2 band have been measured for low J and K values. By combination with lineshift parameters previously published for other frequency ranges, it is possible to consider several level manifolds connected by superabundant numbers of transitions.

β¦ Synopsis
Experimental evidence of inequality of algebraic sums of pressure lineshift parameters of transitions along different paths connecting the same initial and final energy levels in the spectrum of the ammonia molecule is demonstrated. Though such a possibility follows, e.g., from different values of parameters of nearest approach of perturbing molecules b 0 for different transitions in Anderson-type theories (and similar effects in other theories), up to now it lacked experimental evidence. Some consequences of the phenomenon and further studies are discussed.

## Synopsis Studies were made of the influence of hydrostatic pressure on the helix-coil transitions of poly(A + U) and poly(A + 2U). The results were analyzed by a thermodynamic treatment which emphasized the cooperative aspect of the transitions. The helix-to-coil volume changes were found to be
