Portion of the Mbssbauer spectrum for iron—rhodium alloys containing 48 and 50 rhodium

Portion of the myocardium of a rat on a vitamin E-deficient diet for more than a year. Note loss of myocardial fibers, round-cell infiltration, and fibrosis.

Portion of the N2O-HF absorption spectrum taken in a representative panel. The full panel was recorded with a single opening of the pulsed nozzle 50 shots were averaged to improve S N. The upper trace records transmission through a reference cell containing room-temperature N2O. This spectrum shows the linear ONN-HF isomer, with its characteristic P- and R-hranches.

Portion of the NjO-HBr absorption spectrum containing a prominent Q-branch. The etalon trace was taken simultaneously with the N20-HBr spectrum. This spectrum reflects the broadside nature of the complex. Note the change in the horizontal scale relative to

Portion of the one of the functional group trees for addition reactions

Portion of the Palomar spectrum of the bright QSO PHL 957 recorded by Pettini et al. , encompassing the region of the Zn II and Cr II absorption lines in the Jabs 2.3091 DLA. The vertical tick marks indicate the positions of the lines as follows. Line 1

Portion of the periodic table of elements comprising the II-IV, III-V and IV-IV elemental, binary, ternary and quaternary semiconductors and dopants.

Portion of the pol5mieric lattice of an 5-bound thiocyanate rubidium crown ether complex.

Portion of the pol5mieric structure of C7o-7NH3.

Portion of the polymeric sheets formed from association of 2.

Portion of the polymeric species Snl

Portion of the polymeric structure of Cd2 li- r M-NC5H4CH CH

Portion of the proposed infinite hydrogen-bonded sheet of the complex between melamine and isocyanuric acid, lines indicate substructures that might be obtained crystaJlographically by substituting parent compounds to prevent infinite hydrogen bonding.

Portion of the pseudo-two-dimensional extended structure of K
