BACTERIAL IDENTIFICATION BY INFRARED SPECTROPHOTOMETRY II

Portable Refrigerant Identification by Near Infrared Spectrophotometry

Paraffinoma confirmed by infrared spectrophotometry.

Infrared spectrophotometry of enteric bacteria.

Infrared spectrophotometry is rapidly assuming an important place in the biological sciences. Its value derives from the fact that each organic compound has a characteristic and distinct infrared spectrum that can be used to identify it (Randall et al., 1949). The biologist working with cells or tissues is confronted by a highly complex mixture of substances. The infrared spectrum of a cell, th...

Infrared spectrophotometry of M 17 with ISOCAM

We report spectrophotometric observations of the H ii region/neutral medium interface in M 17 obtained with the ISOCAM Circular Variable Filter (CVF) in the spectral range 5.15 to 16.5 m. The lines of singly–ionized species come mainly from the clumpy "neutral" interface, while the H ii region dominates the line emission by higher–ionization species. The emission in the Unidentified Infrared Ba...

Infrared spectrophotometry of NGC 7023 with ISOCAM

We present spectrophotometric observations of the reflection nebula NGC 7023 obtained with the ISOCAM Circular Variable Filter (CVF) in the spectral range 5.15 to 16.5 m. Maps in the 16 m continuum emission and in the Unidentified Infrared Bands (UIBs) have been obtained. The continuum emission peaks at the dense interface between the surrounding molecular cloud and the inner photodissociated r...
