Similarly, iV,A/ -dimethyl-3,3 -bisindolylmethane (169) has been used in a related experiment, where treatment thereof with trifluoroacetic fflihydride (TFAA) in diethyl ether at room temperature yielded a mixture of products from which the trifluoromethyl-substituted indolo[3,2-b]carbazole 170 was isolated as the major pentacyclic component, accompanied by the hydroxy derivative 171 as well as small amounts of the indolo[2,3-h]carbazole 146 (Scheme 20). The precursor 169 could also be prepared in situ from A-methylindol-3-methanol under...

A related experiment TOCSY (Total Correlation Spectroscopy) gives similar information and is relatively more sensitive than the REIAY. On the other hand, intensity of cross peak in a NOESY spectrum with a short mixing time is a measure of internuclear distance (less than 4A). It depends on the correlation time and varies as . It is positive for small molecules with short correlation time (o r <<1) and is negative for macromolecules with long correlation time (wr >>l) and goes through zero for molecules with 1 Relaxation effects should be taken into consideration for quantitative interpretation of NOE intensities, however.

Shimamori and Hatano (1976) describe a Febetron-injected microwave cavity apparatus for measuring electron concentration following pulse irradiation. Its application to thermalization in Ar and CH4 is similar to the method of Warman and Sauer (1975). In a related experiment, Hatano et al. (private communication) measure the electron collision frequency directly. 

In related experiments by Johnson (1985), atomic deuterium was used instead of Hx to neutralize boron in Si. Similar results on spreading resistance were obtained. Furthermore, the distribution profile of D was measured by secondary-ion mass spectrometry (SIMS), as shown in Fig. 4. The distribution profile of D reveals 1) that the penetration depth of D is in good agreement with the resistivity profile and 2) that the D concentration matches the B concentration over most of the compensated region. In another sample, the B was implanted at 200 keV with a dose of 1 x 1014 cm-2, the damage was removed by rapid thermal anneal at 1100°C for 10 sec., and then D was introduced at 150°C for 30 min. As shown in Fig. 5, it is remarkable that the D profile conforms to the B profile. 

TL (a) The N2(g) extracted from liquid air has some Ar(g) mixed in. Only 02(g) was removed from liquid air in the oxygen-related experiments. 

In a related experiment CV-1 fibroblasts were incubated with fluorescent N-Ras lipopeptides bearing a free palmitoylation site. These peptides cause staining of the CV-1 plasma membrane and efficient S-acylation even if the farnesyl group was replaced by a n-octyl group.1271 The association of the N-Ras lipopeptides with the plasma membrane... 

In some related experiments,9 they concluded that ECT did not show any promise in the treatment of leukemia in mice induced by intraperitoneal L1210 tumor tissue implant in other words, ECT is useful for solid tumors only. 

The beginning was not easy," Mark explains, "but related experience in Vienna and the peerless support of Rogers and (Dean R. E.) Kirk made the Institute a quick success." The success was also in part brought about by the labors of a future "who s who" contingent of associates attracted by Mark. A few of the scientists who came to work in the converted razor blade factory which housed the Polytechnic laboratories are T. Alfrey, P. M. Doty, F. Eirich, I. Frankuchen, W. P. Hohenstein, H. Morawetz, C. G. Overberger, C. C. Price,... 

Following are other current and recent-past ventures related to polymer education. A series of experiments appeared in the 1978 Journal of Chemical Education which is aimed at introducing polymer related experiments into traditional courses (7). More of this type of presentation must be forthcoming. 

A y-lactone was formed in excellent yield by the nucleophilic cyclization of a carboxylic acid onto an alkene radical cation generated from a (i-nilrophosphale under tin hydride conditions (Scheme 21) [139]. Related experiments employing the acetate group and an internal carboxylate nucleophile failed, emphasizing the very rapid collapse of the alkene radical cation/acetate ion pair [127]. 

Since highly fluorescent water soluble gold clusters have been synthesized by various routes, they can be used in biology-related experiments such as imaging. These clusters may possess additional benefits over organic fluorophores and fluorescent semiconductor quantum dots. Organic fluorophores are prone to photobleaching,...
