For a fully oriented molecule, the dipolar coupling for an 1 H-15 N amide group would be over 20 kHz, and a pair of protons separated by 5 Å would have up to ~1 kHz coupling. However the degree of alignment achieved by applying magnetic field is so low that the largest 1 H- 15 N or 1 H- 13 C dipolar couplings are <5 Hz. [ 19 ]
Magnetic dipole–dipole interaction, also called dipolar coupling, refers to the direct interaction between two magnetic dipoles. Roughly speaking, the magnetic field of a dipole goes as the inverse cube of the distance, and the force of its magnetic field on another dipole goes as the first derivative of the magnetic field. It follows that ...
In the late 1960s, the Florida Department of Air and Water Pollution Control was created under Governor Claude R. Kirk, Jr. Most staff were being taken from the Bureau of Sanitary Engineering of the state Department of Health. The name of the new agency was simplified to the Florida Department of Pollution Control. [citation needed]
The environment of Florida in the United States yields an array of land and marine life in a mild subtropical climate. This environment has drawn millions of people to settle in the once rural state over the last hundred years. Florida's population increases by about 1,000 residents each day. [1]
There are a number of environmental issues in Florida.A large portion of Florida is a biologically diverse ecosystem, with large wetlands in the Everglades.Management of environmental issues related to the everglades and the larger coastal waters and wetlands have been important to the history of Florida and the development of multiple parts of the economy of Florida, including the influential ...
In nuclear chemistry and nuclear physics, J-couplings (also called spin-spin coupling or indirect dipole–dipole coupling) are mediated through chemical bonds connecting two spins. It is an indirect interaction between two nuclear spins that arises from hyperfine interactions between the nuclei and local electrons. [ 1 ]
The ecology of Florida considers the state's two Level I and three Level II/III ecoregions containing more than 80 distinct ecosystems. [ 1 ] [ 2 ] They differ in hydrology , climate, landforms, soil types, flora, and fauna, forming a global biodiversity hotspot .
The Florida Department of Air and Water Pollution Control was the state of Florida's first agency devoted strictly to environmental quality. It was created under the authority of Florida Statute 69-109 during the administration of Governor Claude Kirk, in 1969. The agency's name was changed to the Florida Department of Pollution Control in 1971
