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]
Aluminium concentrations in young leaves, mature leaves, old leaves, and roots were found to be 8.0, 9.2, 14.4, and 10.1 mg g1, respectively. [3] Melastoma malabathricum L.

The BH-1 was subsequently rebuilt with a Gnome Omega rotary engine and was finally able to fly with two people aboard. It was known as the BH-1 bis in this configuration, and in 1921 won the Czechoslovak national cross-country rally with an average speed of 125 km/h (78 mph) over the 860 km (536 mi) course. The aircraft was damaged in a crash ...
Saturation is most clearly seen in the magnetization curve (also called BH curve or hysteresis curve) of a substance, as a bending to the right of the curve (see graph at right). As the H field increases, the B field approaches a maximum value asymptotically , the saturation level for the substance.
Since common Category 5 cable has four pairs, it is possible to use the spare pairs (pins 4–5, 7–8) in 10- and 100-Mbit/s configurations for other purposes. The spare pairs may be used for power over Ethernet (PoE), for two plain old telephone service (POTS) lines, or for a second 10BASE-T or 100BASE-TX connection.
The chemical formula of beryllium borohydride can be written as Be 2+ ([BH 4] −) 2. The crystal structure is made up of a helical polymer of BH 4 Be and BH 4 structure units. [2] [3] The borohydride ions, [BH 4] −, adopt a tetrahedral geometry. [3] Beryllium is 6-coordinate and adopts a distorted trigonal prismatic geometry. [2]
