    Description / Table of Contents: Infrared and, when possible, RAMAN spectra were recorded from methylene diphosphonates, dihydrogen menthylene diphosphonates, the free acid, and its tetraethyl ester. Frequencies of CH2, P—C—P and PO3 are readily assigned, stretching of the latter being slightly lower than for diphosphates. The hydrogen bonded OH groups are studied further by deuterium exchange and low temperature investigations.
    Notes: Die Infrarot- und soweit möglich die RAMAN-Spektren von Methylendiphosphaten, Dihydrogen-Methylendiphosphaten, der freien Säure und ihrem Tetraäthylester wurden aufgenommen. Die Ch2-PCP-und PO3-Frequenzen sind einfach zuzuordnen, die Valenzschwingungen der letzteren wenig niedriger als für Diphosphate. Die in Wasserstoffbrückenbindungen befindlichen OH-Gruppen werden näher studiert durch Deuteriumaustausch und Untersuchung bei tiefen Temperaturen.
