Title: Production of B.sub.10 H.sub.14 from B.sub.2 H.sub.6 at room temperature by laser induced chemistry using DF laser

Abstract: A method for the production of B.sub.10 H.sub.14 by laser induced chemistry is disclosed. A DF laser is used to irradiate a laser reaction cell containing diborane (B.sub.2 H.sub.6). The P.sub.12 (2611 cm.sup.-1) frequency of the 1-0 band of the DF laser is resonant with the .nu..sub.8 (2614 cm.sup.-1) vibrational fundamental of B.sub.2 H.sub.6 and starts a chain reaction producing solid white crystals of B.sub.10 H.sub.14 that condense on the walls of the laser reaction cell. The method is carried out at room temperature. Thus, the chemical engineering is very simple. The B.sub.10 H.sub.14 produced is of high purity and high yield. The production of decaborane-14 from diborane by DF laser induced chemistry (LIC) represents an efficient synthesis of a large polyatomic molecule of high purity by LIC.
