بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...
15 صفحه اولRotational isomerism in Bis-(p-(3-methyl-butyloxy)-phenyl)-thiourea.
In case of Thiocarlidum (1) the thermoanalytical examination showed an endothermic transformation without loss of weight. This occured in samples recrystallized from cold polar solvents and the transformation proved to be non-reversible. The UV and IR spectra of the two samples differed characteristically and X-ray studies showed that the two modifications (in the following aand ßmodifications ...
متن کاملMethyl 1-phenyl-3-p-tolyl-1,9b-dihydro-3H-chromeno[4,3-c]isoxazole-3a(4H)-carboxylate
In the title compound, C25H23NO4, the pyran ring of the chroman moiety has an envelope conformation with the methyl-ene C atom as the flap. The isoxazole ring has a twist conformation on the O-C bond. The dihedral angle between their mean planes is 57.87 (9)°. The attached phenyl and benzene rings are twisted away from its mean plane by 56.19 (10) and 50.57 (10)°, respectively. These two rings ...
متن کاملSynthesis of a carbon-14 analogue of N-(aryl-methyl)-3-phenyl-acryl amidine-[carboxy-14C] and its derivatives as NR2B-selective NMDA receptor antagonist
Four amidine NR2B-selective NMDA receptor antagonists, N-( 2-methoxy benzyl) -3-phenyl-acrylamidine, N-[diduterio(2-methoxyphenyl) methyl]-3-phenyl-acrylamidine, N-benzyl-3-phenyl-acryl amidine and N-[diduterio(phenyl)methyl]-3-phenyl-acrylamidine, all fourlabeled with carbon-14 in the 1-position, have been synthesized as part of 5-step sequence fromBa14CO3.
متن کامل(Z)-3-Methyl-1-phenyl-4-[(p-tolyl)(p-tolylamino)methylidene]-1H-pyrazol-5(4H)-one
In the title mol-ecule, C(25)H(23)N(3)O(2), the pyrazole ring forms dihedral angles of 28.56 (7), 80.35 (7) and 31.99 (7)° with the phenyl ring, the p-tolyl ring and the p-tolyl-amino ring, respectively. The N-H group attached to the exocyclic C=C bond is in a syn arrangement with respect to the C=O bond of the pyrazolone group and an intra-molecular N-H⋯O hydrogen bond is observed. In the crys...
