Carrier signal

In this paper, the photofragmentation of transition metal cluster complexes is discussed. The experimental information presented concerning the gas phase photodissociation of transition metal cluster complexes comes from laser photolysis followed by detection of fragments by ionization (5.). Ion counting techniques are used for detection because they are extremely sensitive and therefore suitable for the study of molecules with very low vapor pressures (6.26.27). In addition, ionization techniques allow the use of mass spectrometry for unambiguous identification of signal carriers. 

Signaling across synapses may be electrical or chemical. The chemical signal carriers are known as neurotransmitters. They are released from the presynaptic side and recognized by their receptors on the postsynaptic side. 

Atropine is an antagonist for the naturally occurring neurotransmitter (nerve signal carrier) acetylcholine. Its structural similarity to acetylcholine makes it very specific for acetylcholine receptors. How about its effects ... 

A very similar sequence is the ll sequence, which actually belongs to a family of binomial pulse sequences. Of these sequences, the 1331 (often referred to as 1—3) is the most popular due to its wider water suppression window (see Figure l).22 Due to the frequency-dependent sine modulation of the resonance amplitudes (the so-called excitation profile ), the resonances on either side of the water signal (carrier frequency) have opposite signs. In addition, the binomial sequences suffer from baseline distortions due to a strong linear phase gradient (see Figure 1). This baseline distortion can be particularly troublesome in multidimensional experiments and therefore the binomial sequences have not proved popular for multidimensional NMR studies. 

The fitting of space structures of a signal carrier and of a bioreceptor is, as it seems, a decisive factor of a sensory signal occurrence. On the other hand, the formation of unstable effector-receptor complexes is stabilised by non-valency effects. In this way, it is possible to explain a similarity of the character of odour between (-)-a-phellandrene and (-)-limonene [56].
