[10] The spectrum of boron monohydride includes a molecular band for the lowest electronic transition X 1 Σ + → A 1 Π with a band head at 433.1 nm (for 0→0) and 437.1 (for 0→1) [3] The spectrum contains P, Q, and R branches. [10] Although BH is a closed shell molecule, it is paramagnetic independent of temperature. [11]

BH) max can be graphically defined as the area of the largest rectangle that can drawn in the second quadrant of the B-H loop. The maximum energy product is defined based on the magnetic hysteresis saturation loop ( B - H curve), in the demagnetizing portion where the B and H fields are in opposition.
264 Bh, 265 Bh, 266 Bh, and 271 Bh are more stable at around 1 s, and 267 Bh and 272 Bh have half-lives of about 10 s. The heaviest isotopes are the most stable, with 270 Bh and 274 Bh having measured half-lives of about 2.4 min and 40 s respectively, and the even heavier unconfirmed isotope 278 Bh appearing to have an even longer half-life of ...
MG Sports and Racing Europe, based in Eardiston, near Tenbury Wells in Worcestershire, announced the relaunch of the XPower SV in April 2008, under the name MG XPower WR. Priced at between £75,000 and £90,000, the new model had the supercharged engine rated at 540 bhp (403 kW; 547 PS), and seven cars were said to have already been sold. [ 13 ]
Disiamylborane (bis(1,2-dimethylpropyl)borane) is an organoborane with the formula [((CH 3) 2 CHCH(CH 3)) 2 BH] 2 (abbreviation: Sia 2 BH). It is a colorless waxy solid that is used in organic synthesis for hydroboration–oxidation reactions. Like most dialkyl boron hydrides, it has a dimeric structure with bridging hydrides.
In the tail section was a DAG-10 launcher with 10 anti-aircraft or anti-personnel grenades AG-2 (after being thrown, they would fall with parachutes and then burst, but were not widely used in practice). The Il-10 engine was a 12-cylinder inline V engine Mikulin AM-42, liquid-cooled, power: 1,770 hp continuous, takeoff power: 2,000 hp. Three ...
The following is a list of cars marketed under the British MG marque. The marque was owned, and the cars produced, by Morris Garages (1924–1930), M.G. Car Company (1930–1952), British Motor Corporation (1952–1967), British Motor Holdings (1967–1968), British Leyland (1968–1992), Rover Group (1992–2000), MG Rover Group (2000–2006), Nanjing Automobile Group (2006–2011), and MG ...
