...如果是input and output options 的话应该会简写成IOO或IOOp吧,不知楼上的解释出自哪里?

以下是gaussian官方说明:

http://www.gaussian.com/g_tech/g_ur/k_iop.htm

IOp
DESCRIPTION
The IOp keyword allows the user to set internal options (variables in system common /IOp/) to specific values. The syntax is:

IOp(Ov1/Op1=N1,Ov2/Op2=N2, …)

which sets option number Opi to the value Ni for every occurrence of overlay Ovi. Since setting internal options can have arbitrary effects on the calculation, archiving is disabled by use of this keyword.

IOp values explicitly set in the route section are not passed on to the second and subsequent automatically-generated job steps; this applies to keyword combinations like Opt Freq and to inherently multi-step methods such as G2 and the CBS methods. For example, if you want to specify an alternate grid for a DFT optimization+frequency job, you must use an option to the Int=Grid keyword rather than an explicit IOp value.

The execution of each overlay of Gaussian 09 is controlled by numbered options. Each option may be assigned an integer value, with 0 being the default. The value of an option is held unchanged throughout execution of all of the links in one overlay. Thus the significance of a particular option applies to all the component links in one pass through the overlay. The full list of Gaussian 09 options is given in the Gaussian 09 IOps Reference. They are also documented on our web site: www.gaussian.com/iops.htm.

还真没寻思过iop的全称是啥
难道是内部操作进程(internal operation progress)?
iop的作用是提供比keyword对高斯程序更加精确地控制

iop应该是internal option的意思...

因为通常的写法是 IOp,p没有大写,所以应该是和O连在一起的
