    Rotational isomerism inbis carbene MOL4 complexes: A theoretical study (1984)
    Springer
    Theoretical chemistry accounts 64 (1984), S. 461-467 
    Details
    ISSN: 1432-2234
    Keywords: Carbene rotational barriers ; Isolobal analogy ; Ab-initio SCF calculations
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract LCAO-MO-SCF calculations are reported for the different stereoisomers of the Mo(CO)4(CH2)2 and Mo(CO)4[C(NH2)2]2 systems. The substitution of the hydrogen atoms by the amino groups in the carbene ligands leads to an almost zero rotational barrier. Steric interactions are therefore expected to govern the barrier for diaminocarbene ligands which are more bulky than C(NH2)2. The rotational isomerism in thesebis carbene MoL4 systems is also discussed in connection with the isolobal analogy between CH2 and C2H4.

    Effects of myrmicacin (β-hydroxydecanoic acid) on protoplasmic movement and ultrastructure ofCamellia japonica pollen (1981)
    Springer
    Protoplasma 105 (1981), S. 341-345 
    Details
    ISSN: 1615-6102
    Keywords: Golgi-vesicles ; Myrmicacin ; Pollen tube ; Protoplasmic movement
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary While tube elongation of growing pollen ofCamellia japonica was stopped by treatment with 50–100 ppm of myrmicacin, protoplasmic movement in the pollen tube still continued. However, higher concentration (200 ppm) of the inhibitor arrested the movement. The vesicles containing membrane substances disappeared at the tip of the tube of the growth-inhibited pollen. Removal of the inhibitor resulted in the reappearance of the vesicles at the tip region and tube elongation was restored.
