Please prepare your samples in the designated area or under a hood, and not on top of the magnet. The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the ...

Nuclear Magnetic Resonance (NMR) was first experimentally observed in late 1945, nearly simultaneously by the research groups of Felix Bloch, at Stanford University and Edward Purcell at Harvard ...

A major advance in alkene oligomerization catalysis was Brookhart’s 1995 report of highly active group 10 metal diimine systems. In contrast to nickel and palladium catalysts, the corresponding ...

13 C NMR is ideal for organic chemists performing routine molecular analysis. The unique sensitivity and superior resolution of the Spinsolve Carbon enable the power of proton-carbon NMR in a piece of ...

All instruments are capable of multi-dimensional NMR experiments and are non-destructive to the sample. The Bruker 800 MHz Spectrometer utilizes an 18.8 Tesla superconducting magnet and has a sample ...

The following are the recipients of the 2017 National Awards administered by the American Chemical Society (ACS). Vignettes of the award recipients appeared in the Jan. 2, 2017 issue of C&EN. The ...

2M Ibuprofen, 1D proton, single scan, 10 seconds. Neat Diethyl phthalate. 1D Carbon plus three DEPT spectra, total time 10 minutes. 2M Ibuprofen, HSQC-ME, ~1 hour. 2M Ibuprofen, HMBC, ~2 hours. The ...

Editor’s note: This is part of a series called “The Day Tomorrow Began,” which explores the history of breakthroughs at UChicago. Learn more here. Radiocarbon dating, or carbon-14 dating, is a ...

Google says it has wiped out its entire carbon footprint by investing in "high-quality carbon offsets". It became carbon-neutral in 2007 and says it has now compensated for all of the carbon it ...

In this new effort, the researchers were experimenting with light-driven, alkene ... NMR and UV-visible spectroscopy. They also ran their motor in a chamber chilled to –110°C to slow down ...
