Chemical vapors originating from the explosive charge within landmines and unexploded
ordnance (UXO) form a chemical "signature" unique to these devices. The fact that canines …

Preparations of photosynthetic reaction centers from Rhodopseudomonas sphaeroides were
excited with flashes lasting approximately 8 psec. Immediately after the excitation, there …

Lifetimes of excited electronic states of a number of transition metal compounds have been
investigated with picosecond time resolution by following excited state absorption or ground …

Fourier transformed photoacoustic IR spectroscopy of a solid is demonstrated for the first
time. An uncorrected spectrum of polystyrene film shows that the photoacoustic signal from …

Nanosecond and picosecond. kinetic techniques have been used to study electron transfer
from the first excited singlet state (Bph*) and the first excited triplet state (Bph T ) of …

Although much has been written concerning the techniques and benefits associated with
inquiry-based laboratory methods, the use of this approach in both college and secondary …

FTIR and Raman spectroscopic analyses were used to determine the adsorption interaction
between the highly polar organophosphonate dimethyl methylphosphonate (DMMP) and a …

To the Editor, Continuous peripheral nerve blocks are susceptible to various complications,
including leakage from the catheter insertion site which increases the risk of leakage of the …

A new method for the measurement of the primary fluorescence quantum yield of dye solutions
is presented. The method is conceptually and experimentally simple, relying of the S n → …

A wide selection of infrared absorption spectra of opaque samples is presented to show the
versatility of Fourier-transformed infrared photoacoustic spectroscopy. A method for …
