Gamess能量分解对称性的问题

molx79

我做的体系是平面分子ＣＳ对称性，Cs

C,6.0,-0.2220337968,3.2836031701,0.
O,8.0,-1.05003008,2.3941484088,0.
H,1.0,0.8549784362,3.0648815585,0.
H,1.0,-0.5205518851,4.3410737254,0.
S,16.0,-0.5411742307,-0.3855198575,0.
Cl,17.0,-0.3605490628,-2.4131964686,0.
Cl,17.0,1.4131920394,0.1774580734,0.但是在Ｇａｍｅｓｓ中对称性如果定位Ｃｓ，其错误信息为：
...WARNING (SYMORB.SRC)...
THE INPUT BASIS SET CONTAINS APPROXIMATE LINEAR DEPENDENCE.
THE SMALLEST EIGENVALUE OF THE OVERLAP MATRIX IS  -6.966883E+05
THERE ARE   82 EIGENVALUES LESS THAN QMTTOL=  1.00E-06
EIGENVECTORS BELOW -QMTTOL- ARE DROPPED FROM THE MO SPACE,
IN ORDER TO ELIMINATE THE APPROXIMATE LINEAR DEPENDENCE.

THIS WILL MOST LIKELY CHANGE THE ENERGY ON THE ORDER OF TENS OF MICROHARTREES,
DEPENDING ON THE NUMBER OF ORBITALS REMOVED.  THE VALUE OF QMTTOL CAN BE
CHANGED IN $CONTRL: JOBS WITH EIGENVALUES BELOW 1.0E-07 PROBABLY WON'T
CONVERGE.  EIGENVALUES BETWEEN 1.0E-07 AND 1.0E-06 MAY REQUIRE LOOSENING OF
THE DENSITY CRITERION (CONV IN $SCF), MORE ACCURATE INTEGRAL EVALUATION
(ICUT=11 IN $CONTRL), MORE ACCURATE DIRECT SCF FOCK MATRIX
CONSTRUCTION (FDIFF=.FALSE. IN $SCF), OR CHANGING THE SCF CONVERGER
(DIIS=.TRUE. IN $SCF).

SOMETIMES THE ABOVE ERROR IS CASED BY AN INABILITY TO
PROJECT THE HUCKEL GUESS ONTO THE CURRENT BASIS SET,
E.G. WHEN THE 1S HUCKEL ORBITAL OF A H ATOM CANNOT
BE PROJECTED ONTO A PURELY P BASIS SET BECAUSE YOU
ARE TRYING TO DO EXCITED STATE H ATOMS.  IN SUCH A
CASE, PLEASE USE GUESS=HCORE OR GUESS=MOREAD INSTEAD.

如果改为Ｃ１对称性，就能算出来结果。不知道原因，另外Ｃ１对称性计算的结果可靠吗？

当成C1算结果绝对没问题。

谢谢Sob老师。
