A spectrophotometer cuvet is described which is emptied by suction without removal from the instrument. The use of this cuvet saves time and minimizes the chance of breakage. Data from C " measurements and absorbances of a dye solution show minimal retention error from successive specimens. expended in determining the absonbances of a large series of individual samples in a spectrophotometer ca...

CLEMENTINE 2.7 μm DATA AND 70-CM EARTH-BASED RADAR DATA PROVIDE ADDITIONAL CONSTRAINTS FOR UVVIS-BASED ESTIMATES OF TiO2 CONTENT FOR LUNAR MARE BASALTS. J. J. Gillis, P. G. Lucey, B. A.

Tetraaza Macrocyclic complexes of transition metals of Ni (II), Cu(II), Cr(III), Fe(III), Mn(II) were synthesized in methanolic media by template method. The complexes were characterized by elemental analysis, UVVis, Infrared spectroscopy. In vitro antibacterial activity of macrocyclic complexes against five bacteria i.e. Streptococcus mutans, Escherichia coli, Staphylococcus aureus, Streptococ...

Introduction: An accurate phase function is necessary for precise photometric correction of the Clementine lunar UVVIS images. Although several researchers have proposed photometric models for Clementine UVVIS images using empirical phase functions (e.g., [1] [2] [3]), additional work is required for correction of the data at small phase angle (<20), because the phase function at small phase an...
