Absolute intensity measurements have been made on the fundamental vibrations of methyl chloride, bromide, and iodide, and their fully deuterated derivatives, by integrating the optical density over the absorption bands. The bands were fully pressure broadened by using up to 80 atmos of foreign gas. Band separations were made graphically. The results are analyzed in terms of the dipole moment derivatives with respect to symmetry coordinates in the molecule, (∂p/∂Si). The data on the different isotopic species are shown to yield consistent results, and this requirement of consistency has also been used as an aid in the analysis. In the E-class vibrations the signs of the dipole moment derivatives have been determined unambiguously by assuming the permanent dipole to be directed CH3+–X—.

Synopsis Barley yields in three field experiments were increased by nitrogen and sulfur fertilization with a significant nitrogen × sulfur yield interaction. The higher rates of nitrogen fertilization decreased kernel size, increasd barley, malt, and wort nitrogen, and reduced malting quality. Sulfur fertilization had no effect on nitrogen content but increased the enzymatic activities of the malts.

Correlations between all possible pairs of 8 agronomic and 9 malting quality traits were calculated from a population of 102 random lines of the F4 generation from an intervarietal malting barley cross. A strong positive correlation between head erectness and lodging should prove useful for selection purposes, since head erectness can be determined in th absence of differential lodging. Plump barley was negatively correlated with barley color and positively with malt extract. Extract was positively correlated with bushel weight and the wort N/malt N ratio. Beta amylase was positively associated with diastatic power and the beta/alpha ratio. Diastatic power and beta/alpha ratio were positively correlated. Alpha amylase was positively correlated with the wort N/malt N ratio. Alpha and beta amylases were not correlated, indicating that these two traits are independently inherited.Grain yield exhibited no really large correlations with any of the other traits, indicating that it should be possible to select for most quality traits without seriously reducing yield.Correlations among three malting quality and two agronomic traits were compared with published reports by other workers.

a method for the determination of uronic acids 775 by the direct action of hydriodic acid and phosphorus upon the following: 2-quinolone-4-carboxylic acid; hydantoin-( 5|3')-oxindole; hydantoin-(A5,3,)-5',7'-dibromoxindole and 2,5-diketopiperazine-(A3,6,3,,3')-di-(oxindole). The ethyl ester of the acid is formed by the action of tin and alcoholic hydrogen chloride on 2-quinolone-4-carboxylic acid.4. 5-Bromo-isatin, and 5,7-dibromo-isatin will condense with hydantoin and also with diketopiperazine.
